摘要： PROBLEM TO BE SOLVED: To provide excellent water dispersibility without trouble such as clogging of a waste water treatment facility by incorporating setting retarder and water soluble polymer substance in water soluble base material constituted by papermaking water dispersible fiber and water soluble fibrous carboxylalkylcellulose salt. SOLUTION: The hydraulic cement material setting retarding sheet is obtained by incorporating setting retarder and water soluble polymer in water soluble base material constituted by papermaking water dispersible fiber and water soluble fibrous carboxyalkylcellulose salt. Thus, the setting of the surface of the hydraulic cement material molding curable material can be retarded, and can be easily dispersed and removed from the surface of a molding by an automatic washing machine by water injecting. Since the sheet is extremely rapidly dispersed to the size of no fault in a waste water treatment facility, the operating speed of the washing machine can be accelerated.

摘要： PURPOSE:To obtain vapor-permeable and oil-repellent paper having heat resistance, vapor permeability, water absorbability, water resistance, oil repellency and heat-sealing properties, and suitable for use to wrap cooked foodstuffs, frozen foodstuffs, etc., by laminating a vapor- permeable heat-sealing layer and a vapor-permeable non-heat-sealing layer to make a wet web and applying oil-repellent treatment to the resultant wet web with a fluoro-surfactant. CONSTITUTION:This vapor-permeable and oil-repellent paper is manufactured by making a wet web from a papermaking material including thermoplastic multi-branch type fibers and thermoplastic composite fibers, which forms a heat-sealing layer 2, and a papermaking material consisting of papermaking natural fibers or papermaking semi-synthetic fibers, which forms a non-heat-sealing layer 1, and by applying heat treatment under no-pressure or under pressure to the resultant wet web after a fluoro-surfactant is internally added to, or applied to. the wet web. The thermoplastic multi-branch type fibers are such fibers as pulp-like multi-branch type hydrophilic fibers consisting of a thermoplastic resin such as polyethylene. On the other hand, the thermoplastic composite fibers are such fibers as short fibers consisting of two or more kinds of thermoplastic synthetic-resin components having different melting points. This vapor-permeable and oil-repellent paper provides a wrapping material having heat resistance, vapor permeability for water vapor, water absorbability, wet strength, oil repellency and heat-sealing properties either on one face or on both faces, in the case where foodstuffs are heated or defrosted in a microwave oven as they are wrapped in this paper.

摘要： PURPOSE:To enable feed of seeding paper in a wound shape which cannot be fed due to unnecessary tack and improve handleability by providing a tacky agent in a continuous or discontinuous form at a prescribed interval on one surface of base paper having a releasable component for the tacky agent. CONSTITUTION:A coating layer 2 having releasability for a seed tacky agent is provided on readily dispersible paper in water or easily corroded thin paper 1 and a seed tacky agent 4 is the provided on the top surface thereof at a prescribed interval. Thereby, seeds to be sown can be readily peeled even if the tacky agent applied to the seeds to be sown unnecessarily sticks to other sheets of seeding paper.

摘要： PURPOSE:To obtain deodorant having excellent deodorizing effect for offensive odor of nitrogen-base and sulfur-base equally by using a polyvalence metallic salt of high-molecular polycarbonic acid composed of a high-molecular polycarbonic acid and a polyvalence metallic ion as a main agent. CONSTITUTION:The polyvalence metallic salt of high-molecular polycarbonic acid is produced by allowing the high-molecular polycarbonic acid to cause reaction with water-soluble polyvalence metallic ion and exchanging the ion. At that time, a gram equivalent ratio of the polyvalence metallic ion to the carboxyl group of the high-molecular polycarbonic acid is allowed to be in 0.15-1.0. Thus the obtained polyvalence metallic salt of high-molecular polycarbonic acid has more than specified number of carboxyl group forming polyvalence metallic salt, and said salt has powdery or granular form. The salt effectively absorbs and removes the nitrogen-base and sulfur-base offensive odor equally, and is safely and simply used for a home, etc.

摘要： PURPOSE:To obtain an anionic living polymer of a monomer protected with a protective group which can be eliminated only by treatment with a mineral acid or a base, by polymerizing a Schiff base of a specified vinyl monomer in the presence of an anionic polymerization initiator. CONSTITUTION:A vinyl monomer (a) of formula I (wherein R' is H or CH3) is reacted with about 1mol, per mol of component (a), of a 2,6-substituted aniline derivative (b) of formula II (wherein R are each alkyl) at 70-90 deg.C for 1-10hr in the presence of, optionally, 0.1-10mol%, based on component (a), acidic catalyst to obtain a Schiff base (A) of an aromatic vinyl compound. Component A is polymerized at -100 deg.C to room temperature for 0.1-24hr in an inert gas atmosphere or a vacuum in the presence of an anionic polymerization initiator (B) [e.g., (alpha-methylstyrene oligomer) potassium salt] to obtain the title polymer having a number-average MW of 500-500,000 and a weight-average MW to number-average MW ratio of about 1 and having repeating units of formula III (wherein n>=2).

摘要： PURPOSE:To obtain the titled copolymer useful as a reactive resin, etc., by converting a 4-vinylbenzoic acid compound to chloride, reacting with an amino alcohol, cyclizing the product and carrying out living block copolymerization of the resultant styrene derivative containing 4,4-oxazolinyl group with a comonomer. CONSTITUTION:A vinyl monomer of formula I (R is H or methyl; M is H or alkali metal) is made to react with a chlorination agent to form an acid chloride, which is made to contact with an amino alcohol compound of formula II (R and R are alkyl) to obtain an acid amide compound. The compound is subjected to condensation and cyclization in the presence of a chlorination agent to obtain a styrene derivative of formula III containing 4,4-oxazolinyl group. The derivative is added to a living polymer derived from a vinyl monomer of formula IV (R is H or methyl; Z is phenyl, 1-6C alkyl, vinyl, etc.) and block-copolymerized to obtain the objective living block copolymer containing a linkage of the recurring unit of formula V and the recurring unit of formula VI.
