摘要： A filter material comprises a cellulose acetate fiber tow containing 5-50% by weight of a water soluble material and/or a water dispersible material which are soluble in a solvent which dissolves cellulose acetate and which are not compatible with cellulose acetate. Due to the inclusion of the above-mentioned water soluble material and/or water dispersible material in the cellulose acetate fiber, in the presence of moisture, the fiber surface becomes porous by the elution of this water soluble material and/or water dispersible material from the fiber, and the surface area of the fiber is increased. Consequently, the shape of the cellulose acetate fiber tow is easily broken down, and the decomposability of the fiber by microorganisms and the like is increased. When a cigarette filter is made using this type of filter material, a cigarette filter is obtained which has easy decomposability in the natural environment and particularly in water, in atmospheres which contain large amounts of moisture, and the like.

摘要： Disclosed is a non-rigid vinyl chloride polymer composition comprising 100 weight parts of a vinyl chloride polymer resin, 5-50 weight parts of a graft copolymer modifier and 10-300 weight parts of a plasticizer. The graft copolymer modifier is obtained by graft-polymerizing 25-150 weight parts of an alkyl ester of methacrylic acid having 1 to 4 carbon atoms in the alkyl group or a monomer mixture composed of at least more than 50% by weight of said alkyl ester of methacrylic acid onto 100 weight parts of an acrylic elastomer having a swelling degree of 5 to 25 so that the grafting ratio is not larger than 50%. The acrylic elastomer is obtained by polymerizing a mixture comprising an alkyl ester of acrylic acid having 2 to 10 carbon atoms in the alkyl group or a monomer mixture composed of at least 50% by weight of said alkyl ester of acrylic acid, and a polyfunctional crosslinking agent. The non-rigid vinyl chloride polymer composition has excellent weatherability and impact resistance, and exhibits a good molding processability.
