Conjugated diene butyl elastomer copolymer |
| abstract |
A heterogeneous catalytic process for dehydrohalogenating allylically halogenated olefinic hydrocarbon polymers to produce conjugated diene unsaturated polymeric products is disclosed comprising employing certain metal containing catalyst compositions, especially activated alumina supported copper containing catalysts. The process is especially suitable for the preparation of conjugated diene butyl elastomers from halogenated butyl rubber and produces products having relatively high reactivity levels in terms of active diene content. |
