主  题:1,1,3,3-Tetramethyl-1, 3-bis (p-carbomethoxylphenyl) disiloxane Dimethyl bis (p-carbomethoxylphenyl) silane Polyester-polyether Organosilicon modification 

摘      要:A series of Si-containing polyester-polyether multiblock copolymers were synthesizedby transesterification and melt copolycondensation of organosilicon monomers [1, 1, 3, 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.
