Functionalized para-alkylstyrene/isoolefin copolymers and their use in polymer blends |
| abstract |
Functionalized copolymers of a C4 to C7 iso-olefin and para-alkylstyrene are provided which are prepared by a nucleophilic displacement of at least a portion of benzylic halogen present in the alkyl styrene moiety with an S-R2 (OH)n nucleophile, R2 being C¿1? to C20 hydrocarbyl and n being an integer from 1 to 10. Polymer blends based on a mixture of a polar polymer and a functionalized isobutylene/para-alkylstyrene copolymer are also provided, wherein at least a portion of the benzylic halogen present in the alkyl styrene moiety is displaced by OH, S-R?2 (OH)¿n or N(H)2-m((R3)OH)m, R3 being C¿1? to C20 hydrocarbyl and m being 1 or 2. |
