Polymer whiskers composed of p-Oxybenzoyl and p-Mercaptobenzoyl having graded compositions
Preparation of polymer whiskers composed ofp-oxybenzoyl (O) units and p-mercaptobenzoyl (S) units having graded composition was examined by the polymerization of S-acetyl-4-mercaptobenzoic acid (AMBA) and 4-(4-acetoxybenzoyloxy)benzoic acid (OO) or 4-[4-(
FROM CONVENTIONAL TO LIQUID CRYSTALLINE POLYESTERS
To obtain liquid crystalline copolyesters with improved thermal behavior, p-acetoxybenzoyloxy-benzoic acid and a variety of dicarboxylic acids derived from p-hydroxybenzoic acid in combination with acetylated hydroquinone derivatives have been used as poly(ethylene terephthalate) (PETP) modifiers.The influence of the modifier structure on thermotropic properties of the copolyesters and results of dynamic mechanical measurements are discussed.
