SYNTHESISANDCHARACTERIZATIONOFCOMB-LIKEPOLY(ESTERS)CONTAININGSILICONAND/ORGERMANIUMINTHE MAINCHAIN

Poly(esters) derived from the acid dichloride bis(4-chloroformylphenyl)-n-octylmethyl-silane and the diphenols bis(4-hydroxyphenyl)-2,2-propane (bisphenol A), bis(4-hydroxyphenyl)-dimethylsilane and germane were synthesized under phase transfer conditions and characterized only by IR spectroscopy du...
