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.
Silylketene醇醚,包括“活性”GTP聚合物,可以在GTP有效催化剂的存在下与酰基或磺酰基化合物酰化或磺酰化,从而产生β-
酮酸酯或β-磺酰酸酯; 可以制备聚合物产品,包括帽子,偶联和链扩展聚合物和嵌段共聚物。
