INTERPOLYMER CURES OF BLENDS COMPRISING HALOGENATED ISOOLENFIN/PARA-ALKYLSTYRENE ELASTOMERS AND UNSATURATED ELASTOMERS. |
摘要 |
Vulcanizable blends containing a halogenated copolymer of a C4-C7 isomonoolefin and para-alkylstyrene mixed with one or more olefinically unsaturated elastomeric polymers are disclosed. Cure is preferably effected using zinc stearate as a curative at levels below about 3.0 phr which gives rise to vulcanizates having selective interpolymer addition of benzylic halogen present in the halogenated copolymer to the double bond of the unsaturated polymer with no significant self curing of the halogenated polymer taking place.
