ELASTOMER OF CO-POLYESTER POLYMER

摘要

A) mixing and reacting dibasic acid of formula (I) for forming ester monomer and short-carbon ring diol, dibasic acid of (II) for long-rings ether monomer and long-rings diol of (III), photo stabilizer, and tetrakis(methylene-3(3',5'-di-tert-butyl-4'-hydroxyphenyl)propionate)methane as a antioxidizer; and B)polymerization. In formula, R is a radical which is removed carboxyl group from dibasic acid; B is a radical which is removed of hydroxyl group from short-rings diol; and G is a radical removed of hydroxyl group from long-rings diol. The copolyester elastomer has good anti-weathering properties using 2-(2H-benzotriazole-2-yl)-4-methyl-6-dodecylphenol as a photo stabilizer.
