Abstract

The effect of a polyethylene blend composition and concentration of polar components of ethylene copolymers with vinyl acetate and copolymers of ethylene/vinyl acetate/maleic anhydride on some properties of high-pressure polyethylene compositions with these copolymers is discussed. It is shown that, for the blends under investigation, the character of the adhesive strength dependence determines the vinyl acetate content in the polar copolymer. It is established that the presence of anhydride units in the polar copolymer increases the absolute adhesive strength of the composition without affecting the nature of its dependence on composition of the polyolefin blend.

聚乙烯与极性共聚物共混物的一些粘附性和物理机械性能

摘要

讨论了聚乙烯共混物组成和乙烯与乙酸乙烯酯共聚物和乙烯/乙酸乙烯酯/马来酸酐共聚物的极性组分浓度对具有这些共聚物的高压聚乙烯组合物的一些性能的影响。结果表明，对于所研究的共混物，粘合强度依赖性的特征决定了极性共聚物中乙酸乙烯酯的含量。已确定极性共聚物中酸酐单元的存在增加了组合物的绝对粘合强度而不影响其对聚烯烃共混物组成的依赖性的性质。
