Polymeric materials modified with about 0.1 to 10, preferably 2 to 8, percent by weight of certain halofunctional monomeric materials substantially improve adhesion between an elastomeric substrate and a metal surface by improving bonding performance at the elastomer-adhesive interface and by eliminating the need for relatively large amounts of additional adhesive components such as nitroso or carbamate compounds. A preferred embodiment of the invention involves a copolymer derived from a halobutadiene monomer and α-halo-substituted monomeric compounds wherein the α-halo-substituted compound is present in an amount from about 0.1 to 10, preferably 2 to 8, percent by weight of the copolymer. A typical halobutadiene monomer is 2,3-dichlorobutadiene-1,3, while typical α-halo-substituted compounds include α-chloroacrylonitrile, α-bromoacrylonitrile, ethyl-α-bromoacrylate, and ethyl-α-chloroacrylate.
用约 0.1%至 10%,最好是 2%至 8%(按重量计)的某些卤官能团单体材料改性的聚合材料,通过改善弹性体-粘合剂界面的粘合性能和消除对相对大量的附加粘合剂成分(如亚硝基或氨基甲酸酯化合物)的需要,大大改善了弹性体基材和金属表面之间的粘合性。本发明的一个优选实施方案涉及一种由卤化丁二烯单体和α-卤代单体化合物衍生的共聚物,其中α-卤代化合物的含量约为共聚物重量的 0.1%至 10%,最好为 2%至 8%。典型的卤代丁二烯单体是 2,3-二氯丁二烯-1,3,而典型的 α-卤代化合物包括 α-氯丙烯腈、α-溴丙烯腈、乙基-α-溴丙烯酸酯和乙基-α-氯丙烯酸酯。
