    摘要: Silylketene acetals, including "living" GTP polymers, are acylated or sulfonylated in the presence of GTP-effective catalysts with acyl or sulfonyl compounds to produce .beta.-ketoesters or .beta.-sulfonylesters; polymeric products, including capped, coupled and chain-extended polymers and block copolymers can be prepared.
