Comb-block copolymers of isobutylene copolymer backbone with functional polymer comb arms
Comb-block copolymers of isobutylene copolymer backbone with functional comb arms, methods for making a comb-block copolymer comprising polymerizing one or more monomer components comprising units derived from at least one of acrylates, vinyl terminated C6 to C20 aromatics, acrylamides, and acrylonitrile using a halogenated copolymer initiator having a benzylic-halide moiety via atom transfer radical polymerization (ATRP) in the presence of a transition metal complex catalyst at a temperature ranging from 30° C. to 150° C., the use of these comb-block copolymers as a tire tread additive, as a nanofiller dispersant in elastomeric nanocomposite compositions comprising halobutyl rubber, as a surfactant, as a sealant, and as an additive in a latex formulation is disclosed.
