摘要

Phenyltrichlorosilane was hydrolyzed both ifi. toluene and in ether from which two kinds of prepolymers were obtained with different structures

molecular weights

and molecular weight distributions. Polymers were prepared from the prepolymers in various polymerization conditions. The ladderlike

branched

and crosslinked structures formed under different polymerization conditions were characterized by means of FTIR

1H and 29Si-NMR

and elemental analysis. Azeotropic distillation of solvents and H2O from the system and high molecular weight products with perfect ladderlike structure were obtained.
