Star-shaped copolymers having three different branches, poly(styrene), poly(dimethylsiloxane), and poly(tert-butyl methacrylate), were prepared by coupling of poly(styryl) anion with end-reactive poly(dimethylsiloxane), followed by anionic propagation of tert-butyl methacrylate. End-reactive poly(dimethylsiloxane) was prepared by anionic polymerization of hexamethylcyclotrisiloxane initiated with the lithium salt of p-(dimethylhydroxy)silyl-~-phenylstyrene. The resultant polymers were characterized by osmometry, g.p.c., 1H-n.m.r., and found to be pure and to have narrow molecular weight distributions
