The composition according to the invention includes:
A - 100 parts by weight of an ABS polymerizate which has a rubber content of between 5 and 30 parts by weight and which may contain up to 60 per cent by weight of alpha-methylstyrene; and
B - 0.1 to 12 parts by weight of at least one polyester corresponding to the formula:
in which:
R1 and R2, which are identical or different, denote a hydrogen atom or a C1-C20 alkyl radical;
R3 and R4, which are identical or different, denote a hydrogen atom or a C1-C4 alkyl radical;
R5 and R6 denote a C1-C6 alkylene radical;
x is an integer from 1 to 4; and
n has a value such that the number-average molecular mass of the polyester is between 800 and 7000.
根据本发明的组合物包括
A - 100 份(按重量计)ABS 聚合体,其橡胶含量在 5-30 份(按重量计)之间,α-甲基苯乙烯含量可达 60%(按重量计);以及
B - 0.1 至 12 份(按重量计)至少一种聚酯,其分子式如下
其中
相同或不同的 R1 和 R2 表示氢原子或 C1-C20 烷基;
相同或不同的 R3 和 R4 表示氢原子或 C1-C4 烷基;
R5 和 R6 表示 C1-C6 亚烷基;
x 是 1 到 4 的整数;以及
n 的值使聚酯的平均分子质量介于 800 和 7000 之间。
