A melt kneaded mixture is formed of, by wt,
(A) 100 parts of a poly-α-olefin (e.g. polypropylene);
(B) 1 to 20 parts of an ethylene copolymer having a melt index as defined in JIS-6760 at 190°C of 1 to 1,000 g/10 mins, produced by high pressure continuous polymerization with a free radical catalyst of
(a) 40 to 95% of ethylene and
(b) 5 to 60% of at least one dialkylaminoalkyl acrylamide comonomer represented by the formula:
wherein R₁ is H or -CH₃; R₂ and R₃ each is hydrogen or C1-4 alkyl; and n is 2 to 4;
and optionally up to 20 wt% of an unsaturated ester
(C) 0 to 3 parts of at least one alkali metal salt of a C7-24 organic carboxylic acid (e.g. a stearate); and optionally other additives.
This composition can be melt spun into fibers or fabricated into other products, all of which are easily dyed especially with anionic dyes, alone or with other fibers.
熔融捏合混合物由以下物质组成(按重量计): 1、
(A) 100 份聚α-烯烃(如聚丙烯);
(B) 1 至 20 份乙烯共聚物,其熔融指数如 JIS-6760 中所定义,190°C 时为 1 至 1,000 克/10 分钟,该共聚物是在下列自由基催化剂的作用下,通过高压连续聚合反应制得的
(a) 40% 至 95% 的乙烯和
(b) 5%至 60%的至少一种二烷基氨基烷基丙烯酰胺共聚单体,其分子式为
其中 R₁ 是 H 或 -CH₃;R₂ 和 R₃ 各自是氢或 C1-4 烷基;n 是 2 至 4;
以及任选高达 20 wt%的不饱和酯
(C) 0 至 3 份至少一种 C7-24 有机羧酸的碱金属盐(如硬脂酸盐);以及可选的其 他添加剂。
这种组合物可以熔融纺成纤维或制成其他产品,所有这些产品都很容易染色,尤其是单独或与其他纤维一起使用阴离子染料染色。
