    摘要: A blend of chlorinated polyethylene with two or more different ethylene/vinyl acetate copolymers is provided. The blend produces a membrane which is suitable for use in single-ply roofing applications. One ethylene/vinyl acetate copolymer has a polymerized vinyl acetate content of from about 38 to about 60 percent by weight of copolymer. A second ethylene/vinyl acetate copolymer has a polymerized vinyl acetate content of from about 13 to about 27 percent of weight of copolymer.
