Abstract

The discovery that certain alkylaluminum compounds (e.g. Et2AlCl, Et3Al, Me3Al, etc.) in conjunction with suitable alkyl halides (e.g. tBuCl, PhCH2Cl, etc.) are efficient initiating systems for the polymerization of isobutylene, styrene, etc. provides the basis for novel efficient cationic graft synthesis. By an extension of our mechanism developed to rationalize initiation in homopolymerization systems, it was postulated and demonstrated that graft copolymerizations could be initiated by suitable macromolecular halides in the presence of suitable alkylaluminum compounds:
$$ P - Cl + M{e_3}Al \rightleftharpoons {P^ \oplus }MeAlC{l^\Theta }P{M^ \oplus } \to graft $$
where PCl is a macromolecular halide initiator such as chlorobutyl rubber or polyvinyl chloride and M is a cationically polymerizable monomer.
