Graft copolymers containing ionomer units |
摘要 |
Graft copolymers having cationic units pendant to the backbone chain are disclosed. These polymers are prepared by reacting a polymer containing halogenated para-methylstyrene units in the chain, e.g., a brominated copolymer of isobutylene and para-methylstyrene, with an anionically polymerized polymer made using an organolithium initiator compound having the formula R1 R2 Z R3-Li where R1 and R2 are alkyl radicals, R3 is a direct link or an organic radical and Z is nitrogen or phosphorous. Reaction of the anionically polymerized polymer having an R1 R2 Z R3- end group with the halogenated polymer leads to graft polymers coupled by a quaternary ammonium or phosphonium groups.
