## Abstract **Summary:** Star‐shaped hydroxy‐terminated poly(__ε__‐caprolactone)s (__ss__PCL), with arms of different lengths, were obtained by ring‐opening polymerization (ROP) of __ε__‐caprolactone initiated by pentaerythritol, and were condensed with __α__‐methyl‐__ω__‐(3‐carboxypropionyloxy)‐po
Block copolymers of polysulfone-poly(alky1ene oxide)-poly(dimethylsi1oxane) have been prepared by the addition of preformed a,w-bis(hydrogensily1) poly(dimethylsi1oxane) oligomers to allyl end-capped poly(alky1ene oxide)-polysulfone. The hydrosilylation reaction, catalyzed by platinum, was employed
