Abstract
A composition for an interlayer film of a laminated safety glass, said composition comprising (A) a thermoplastic resin resulting from copolymerization of (1) vinyl chloride, (2) glycidyl methacrylate and (3) at least one monomer selected from the group consisting of ethylenic hydrocarbons, vinyl esters of fatty acids, acrylic esters and vinyl ethers, and (B) a plasticizer.
Claims2
An interlayer for a laminated safety glass, said interlayer comprising (A) a thermoplastic resin resulting from copolymerization of (1) 80 to 98.5% by weight of vinyl chloride, (2) 1 to 10% by weight of glycidyl methacrylate and (3) 0.5 to 10% by weight of ethylene, (B) 10 to 40% by weight of a plasticizer, and (C) 1 to 10 parts by weight of an organotin stabilizer per 100 parts by weight of said thermoplastic resin.
