Abstract:
1. A copolymer comprising (a) at least one polymer block comprising a plurality of constitutional units that correspond to at least one cationically polymerizable isomonoolefin species and (b) at least one polymer block comprising a plurality of constitutional units that correspond to at least one anionically polymerizable monomer species selected from the group consisting of monomers of formula (I): wherein R n is an integer of 1 or 2; p is an integer of 0 or 1; M is a metal; X is a counterion; and L is one or more ancillary ligands; and (c) at least one functional group selected from allyl and silyl, wherein the functional group is located between at least one cationically polymerizable isomonoolefin species and at least one anionically polymerizable monomer species.
