SYNTHESIS OF ELASTOMERS CONTAINING SI-N BONDS IN THE MAIN CHAIN.
Abstract
Hydrolytic stabilities of silazane monomers and polymers are correlated with chemical structure, and the requirements for hydrolytically stable structures are defined. New polymers with phenyl or ethyl groups substituted on silicon are described. The ethyl-substituted monomers underwent crosslinking reactions during polymerization and did not give soluble polymers. Thermogravimetric analyses of the phenyl-substituted polymers showed that they are considerably less thermally stable than the methyl-substituted polymers. A series of comparative thermogravimetric analyses in air and nitrogen did not reveal a lack of oxidative stability in the polymers. (Author)
