摘要： Disclosed are random copolymers derived from ethylene and at least two different alkyl acrylate comonomers, with or without an acid cure site-containing comonomer. In particular, disclosed are copolymers derived from copolymerization of (a) from 10 to 50 weight % of ethylene; (b) from 5 to 55 weight % of a first alkyl acrylate; (b) from 15 to 80 weight % of a second alkyl acrylate; and (d) from 0 to 7 weight % of a monoalkyl ester of 1,4-butene-dioic acid. Such copolymers exhibit lower glass transition temperatures (Tg) relative to previous ethylene copolymers comprising a single alkyl acrylate comonomer and maintain the good heat and fluid resistance when employed to produce cured elastomeric compositions as well as the improved low temperature properties. This invention also provides compounded compositions comprising these copolymers, and cured compositions (i.e., vulcanizates) as well as rubber articles formed from these compounded compositions, such as hoses, dampers, seals, gaskets, constant velocity joint (CVJ) boots and shaft boots.
摘要翻译：公开了衍生自乙烯和至少两种不同的丙烯酸烷基酯共聚单体的无规共聚物，具有或不具有含酸固化位点的共聚单体。特别地，公开了衍生自（a）10至50重量％的乙烯的共聚合的共聚物; （b）5至55重量％的第一丙烯酸烷基酯; （b）15至80重量％的第二丙烯酸烷基酯; 和（d）0至7重量％的1,4-丁二烯酸的单烷基酯。这种共聚物相对于包含单一烷基丙烯酸酯共聚单体的先前乙烯共聚物显示较低的玻璃化转变温度（Tg），并且当用于产生固化的弹性体组合物以及改进的低温性能时，保持良好的耐热和耐流体性。本发明还提供了包含这些共聚物和固化的组合物（即硫化橡胶）的复合组合物以及由这些复合组合物形成的橡胶制品，例如软管，阻尼器，密封件，垫圈，等速万向节（CVJ）靴和轴靴。

摘要： An adhesive composition comprising a melt blend of: (a) 50-95 % by weight of polypropylene that has been grafted with 0-5 %, especially at least 0.1 % by weight, of at least one ethylenically-unsaturated carboxylic acid or anhydride, or derivative thereof; and (b) 5-50 % by weight of at least one copolymer of ethylene and at least one comonomer selected from carbon monoxide, vinyl acetate, alkyl acrylates, alkyl methacrylates, in which the alkyl group has 1-4 carbon atoms, acrylic acid and methacrylic acid, and ethylene/propylene/diene copolymers, said copolymer having been grafted with 0-5 % by weight of at least one ethylenically-unsaturated carboxylic acid or anhydride, or derivative thereof. The adhesive composition has a melt viscosity suitable for use as a hot melt adhesive.
