Abstract
Condensation polymers were prepared starting from difunctional silicon-containing carboxylic acids or diols. Dimethyl bis(p-carboxymethylphenyl)silane was condensed with various diols to yield polyesters and with various diamines and diisocyanates to yield polyamides. Dimethyl bis(p-carboxymethylphenyl)silane and dimethyl bis(p-hydroxymethylphenyl)silane were condensed with dicarboxylic acids to yield polyesters, with diisocyanates to yield polyurethanes, and with ethyl chloroformate to yield a polycarbonate. Some of the properties of the polymers were compared with those of the corresponding polymers prepared from dimethyl bis(p-carboxyphenyl)silane.
