US5290865A Process for producing a lactam compound graft copolymer of ethylene copolymer 失效
制备乙烯共聚物的内酰胺化合物接枝共聚物的方法

Process for producing a lactam compound graft copolymer of ethylene copolymer
摘要：
A process for producing a graft copolymer comprising melt-blending:(A) 1 to 90 parts by weight of an ethylene copolymer, based on the weight of the graft copolymer, comprising (a) 40 to 99.9% by weight of ethylene units, (b) 0 to 60% by weight of .alpha.,.beta.-unsaturated carboxylic acid alkyl ester units, and (c) 0.1 to 10% by weight of maleic anhydride units;(B) 0.1 to 10 moles of a lactam metal salt compound per mole of the maleic anhydride units (c) of the ethylene copolymer (A); and(C) 10 to 99 parts by weight of a lactam compound, based on the weight of the graft copolymer,which results in a graft copolymer having high impact strength, high flexibility, satisfactory dyeability, and well-balanced physical properties over a wide temperature range.
摘要（中）：

一种制备接枝共聚物的方法，包括熔融共混：（A）1-90重量份乙烯共聚物，基于接枝共聚物的重量，包括（a）40-99.9重量％的乙烯单元，（ b）0至60重量％的（α），（β-）不饱和羧酸烷基酯单元，和（c）0.1至10重量％的马来酸酐单元; （B）每摩尔乙烯共聚物（A）的马来酸酐单元（c）为0.1〜10摩尔的内酰胺金属盐化合物; 和（C）10至99重量份的内酰胺化合物，基于接枝共聚物的重量，其导致接枝共聚物具有高冲击强度，高柔性，令人满意的可染性和在宽的物理性能上的良好平衡 温度范围。
