摘要： PROBLEM TO BE SOLVED: To provide a method capable of recovering ε-caprolactam efficiently while preventing the oligomerization and thermal decomposition of the ε- caprolactam, and recovering the ε-caprolactam from a residue discharged from a polymerization vessel containing the oligomers of the ε-caprolactam, and to provide a facility for the recovery. SOLUTION: This method for recovering ε-caprolactam comprises recovering the ε-caprolactam from an ε-caprolactam oligomer-containing residue discharged from a polymerization vessel in a process for polymerizing monomers containing at least the ε-caprolactam to produce a polyamide. Therein, the residue is brought into contact with a high temperature high pressure water at temperature of 280-450 deg.C water a pressure of 100-500 kg/cm2 to depolymerize the ε- carpolactam oligomer to recover the ε-caprolactam. The facility is provided with a reactor 1 and with a post-treatment means 2 for post-treating the product discharged from the reaction vessel 1 to recover the ε-caprolactam.

摘要： PURPOSE:To provide the subject adhesive comprising the combination of a radically polymerizable monomer, an itaconic acid monoester compound, an alpha-ketocarbonyl compound and a reducing agent, having the characteristics of good hardness, compression strength and water absorbability, and having excellent adhesive forces to dentines and enamels. CONSTITUTION:The photocurable adhesive excellent in the photocurability in a low temperature region near to the ordinary temperature and under a humid condition and in the water-resistant adhesivity of the cured product comprises a radically polymerizable monomer (e.g. methyl acrylate), an itaconic acid monoester of formula I (R1 is H, CH3; R2 is alkylene, oxyalkylene, etc.) (e.g. a compound of formula II), alpha-ketocarbonyl compound (e.g. diacetyl, benzyl, camphor-quinone) and a reducing agent (e.g. N-phenylglycine). The adhesive contains the itaconic acid monoester as a main component, and has an excellent adhesive force to dentines due to the actions of the itaconic acid residue and other functional groups in the compound, while maintaining the adhesive force to enamels.

摘要： PURPOSE:To obtain the title packing agent which can be applied to teeth immediately after eruption to promote dentinal maturation after eruption by using a combination of tetracalcium phosphate dust, a fluoride, citric acid and/or tartaric aqueous solution. and an aqueous solution of an unsaturated carboxylic acid copolymer. CONSTITUTION:The title cavity fissure-packing agent is composed of (A) a tetracalcium phosphate powder, (B) a fluoride, preferably calcium fluoride or strontium fluoride, (C) an aqueous solution of citric acid and/or tartaric acid and (D) an aqueous solution of an unsaturated carboxylic acid copolymer, preferably an acrylic acid-itaconic acid copolymer. Since it hardens even under simple (not strict) water-proof conditions, the packing agent can be applied to teeth immediately after eruption (the teeth is difficult in the rubber dam sealing). Further, their dentinal maturation is promoted after eruption and low concentration of F is fed to the dentine for a long period of time, as Ca and P concentrations in the packed fissure is kept high. Thus, the agent has effect of not only the dentinal maturation, but also recalcification of initial tooth decay and the dentinal strengthening.

摘要： PURPOSE:To enhance the adhesion between a bicomponent prosthetic material having low odor, low stimulation and low heat and those to be fixed which is made of a polymethacrylic acid resin (PMMA) denture or a sulfonic resin (PSF) denture by using (meta-)acrylic ester with two and more functional groups as a pretreatment agent. CONSTITUTION:A molding panel made of PMMA denture material or a molding panel made of PSF denture material is cut and soaked in a 37 deg.C water for 60 hours and then the surface is polished. Several types of (meta-)acrylic ester with two and more functional groups used as a pretreatment agent is applied to the surface 5 to be adhered uniformly. A plastic ring 3 is filled with a ground bicomponent prosthetic material 6 and a metal hook 7 is inserted therein before the bicomponent prosthetic material 6 is cured and fixed therein. Ten minutes later, the material 6 is soaked in a 37 deg.C water and is taken out in 24 hours. Thus, the adhesion enough to adhere a polysulfonic resin denture is obtained.

摘要： PURPOSE:To provide the subject adhesive for dental use, excellent in adhesiveness to the dentine, retaining high adhesivity for a long period of time even in water or saliva, also good in durability in the oral cavity. CONSTITUTION:The objective adhesive containing essentially (A) a radical- polymerizable monomer such as 2-hydroxyethyl (meth)acrylate, (B) a maleic monoester compound of formula I (R1 and R2 are each H or CH3; m and n are each 1, 2 or 3), e.g. a compound of formula II-V, (C) an alpha-ketocarbonyl compound, pref. alpha-diketone, esp. diacetyl, benzil or camphorquinone, and (D) a reducing agent such as ethyl p-dimethylaminobenzoate. The preferable amounts of the above components are as follows: (1) 10-100 (esp. 20-90)wt.% of the component B based on the other polymerizable monomers, and (2) normally each 0.1-5wt.% of the components C and D based on the components A plus B. This adhesive is excellent in photocurability over a relatively low temperature range near normal temperature and in a wet state, and also excellent in the water- resistant adhesiveness of the cured product therefrom.
