Graft copolymers of a bisphenol-A-based polyhydroxyether (phenoxy) and polydimethylsiloxane (PDMS) were prepared by ( 1 ) the reaction of phenoxy and chlorosilyl-terminated PDMS, and (2) the heterogeneous Pt-catalysed hydrosilation of allyl-derivatized phenoxy with hydrosilyl-terminated PDMS. The monofunctional PDMS oligomers were prepared by the anionic polymerization of hexamethylcyclotrisiloxane (D3) using n-BuLi as initiator and chlorodimethylsilane (CDMS) or dichlorodimethylsilane (DCDMS) as terminating agent. The copolymers were characterized by 1H and 13C n.m.r, spectroscopy, gel permeation chromatography (g.p.c.), t.g.a., d.s.c., and i.r. spectroscopy
