A transparent polyether-ester amide having a permanently antistatic property is obtained by copolymerizing (a) an aminocarboxylic acid, a lactam, or a salt derived from a diamine and a dicarboxylic acid; (b) a dial of the formula:
and
wherein R1 and R2 are an ethylene oxide or propylene oxide group, Y is covalent bond, alkylene, alkylidene, cycloalkylidene, arylalkylidene, 0, SO, SO2, CO, S, CFz , C(CF3)2 or NH, X is H, alkyl, halogen, sulfonic acid or salt thereof, ℓ is 0 or an integer of 1 -4, and m and n an integer of 1 - 15; (c) a poly(alkylene oxide)glycol or a diol of the formula:
wherein R3 is alkylene, alkylidene, cycloalkylidene or arylalkylidene; and (d) a dicarboxylic acid; wherein the content of the polyether-ester units is 10 to 90 wt.%. The polyether-ester amide is used preferably as a blend thereof with a graft copolymerization product formed by graft-polymerizing (a) a rubbery polymer with (b) a monomer mixture of a methacrylic or acrylic acid ester, an aromatic vinyl monomer and an optional vinyl cyanide monomer, this product having a refractive index approximately similar to that of the polyether-ester amide.
一种具有永久抗静电特性的透明聚醚酯酰胺是通过共聚以下物质而获得的:(a) 氨基羧酸、内酰胺或由二胺和二羧酸衍生的盐;(b) 式中的转盘:
和
其中 R1 和 R2 是环氧乙烷基团或环氧丙烷基团,Y 是共价键、亚烷基、亚烷基、亚环烷基、亚芳基、0、SO、SO2、CO、S、CFz、C(CF3)2 或 NH,X 是 H、烷基、卤素、磺酸或其盐,ℓ 是 0 或 1 -4 的整数,m 和 n 是 1 - 15 的整数; (c) 式中的聚环氧烷二醇或二元醇:
其中 R3 为亚烷基、亚烷基、亚环烷基或亚芳基烷基;以及 (d) 二羧酸;其中聚醚酯单元的含量为 10 至 90 wt.%。聚醚酯酰胺最好与接枝共聚产物混合使用,该接枝共聚产物是由(a)橡胶聚合物与(b)甲基丙烯酸酯或丙烯酸酯、芳香族乙烯基单体和任选乙烯基氰单体的单体混合物接枝共聚而成,该产物的折射率与聚醚酯酰胺的折射率大致相似。
