SILICON-CONTAINING AROMATIC POLY(ESTERS) DERIVED FROM BIS(4-CARBOXYPHENYL)METHYL-R-SILANE AND BIS(4-(HYDROXYMETHYL) PHENYL)METHYL-R-SILANE: SYNTHESIS, CHARACTERIZATION AND THERMAL STUDIES
This work describes the synthesis, characterization and thermal studies of poly(esters) (PEs) containing two Si atoms in the main chain, derived from aromatic diacids and aliphatic dialcohols in which the Si atom is bonded to methyl and/or ethyl groups. PEs were characterized by FT-IR and ¹H, 13C an...
