Title:		Virtually Telechelic Silyl-functional polyisobutylene
Inventor:		Rudolf Faust
Summary:		This patented invention relates to functionalized monomers that can be polymerized into rubbery polymers having low hysteresis and good compatibility with fillers, such as carbon black and silica. The functionalized monomers of this invention are incorporated into the rubbery polymer by copolymerization with one or more conjugated diolefin monomers and other monomers that are copolymerizable, such as vinyl aromatic monomers. The patented method for preparing a moisture-curable, virtually telechelic, silyl-functional polyisobutylene is disclosed. The method comprises reacting, in the presence of a Lewis acid, isobutylene; an polymeric initiator, and a styryl comonomer having a divalent non-aromatic hydrocarbon group having 1 to 6 carbon atoms, and alkyl groups having 1 to 10 carbon atoms or aryl groups having 6 to 10 carbon atoms, and having a divalent non-aromatic hydrocarbon group having 2 to 6 carbon atoms.
