摘要:
A living carbocationic catalyst composition comprising an initiator of a tertiary alkyl halide, a tertiary aralkyl halide or polymeric halide a co-initiator of a methylaluminum or methylboron compound, and a solvent medium with a dielectric constant between 2.5 and 7 is used to produce narrow molecular weight distribution polymers particularly isobutylene polymers.
