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.
