摘要

正

A series of Si-containing polyester-polyether multiblock copolymers were synthesizedby transesterification and melt copolycondensation of organosilicon monomers [1

3-tetramethyl-1

3-bis （p-carbomethoxyphenyl） disiloxane] （I ） or dimethyl bis （p-carbometh-oxyphenyl） silane]

（II） and dimethyl terephthalate （DMT）

with 1

4-butanediol

poly-tetramethylene glycol （PTMG） respectively. The organosilicon monomers were preparedby Grinard reaction

oxidation and esterification. The structures of the above monomers（I）

（II） and the copolymers were characterized by MS anal. and

H-NMR.
