## Abstract Block copolymers were synthesized by the condensation of dihydroxyl‐terminated poly‐(α‐methylstyrene) oligomers and bisdimethylamino‐terminated poly(dimethylsiloxane) oligomers. Manipulation of block molecular weight produced copolymers ranging in composition from 21% to 73% poly(dimeth

## Abstract Poly(4‐vinylpyridine)‐b‐Poly(dimethylsiloxane) (P4VP‐b‐PDMS) copolymers have been synthesized by sequential anionic polymerization of 4VP and hexamethylcyclotrisiloxane at — 70°C. The initiator was sodium naphthenate. The solvent used during reactions has a very critical role in an homo
Block copolymers composed of poly(dimethylsi1oxane) segments linked to polypeptide have been synthesized by reacting primary mine-terminated silicone with N-carboxy anhydrides of amino acids. The mine-terminated silicone was prepared by reacting "living" polysilanolate with y-aminopropyltriethoxysil
