Abstract

This study concerns the preparation and characterization of a new graft copolymer comprising polychloroprene backbone and polyisobutylene branches which carry tertiary chlorine termini. Synthesis involved the grafting of isobutylene from polychloroprene by the use of BCl//3 coinitiator in methylene chloride solvent in the minus 12 to minus 78 degree C range. Conditions have been defined for efficient and convenient graft copolymerizations. Carefully purified grafts (selective solvent extraction) were characterized by a battery of analytical techniques including **1H-NMR spectroscopy and GPC.
