Abstract: Thermostable polyesters of formula (I) wherein n is 40-200, and the carbonyl and carboxy groups on the pheylene radical are in para or meta positions with respect to each other. The polyesters are useful as electrically insulating materials. They are produced by reaction of diacylchlorides of terephthalic or isophthalic acid with 4,4''-dihydroxytetraphenylmethane.
Abstract translation: 式（I）的热稳定性聚酯，其中n为40-200，并且所述亚乙基上的羰基和羧基相对于彼此处于对位或间位。 聚酯可用作电绝缘材料。 它们通过对苯二甲酸或间苯二甲酸的二酰氯与4,4'-二羟基四苯基甲烷的反应制备。

CPC classification number: C08G73/1003
Abstract: NEW AND IMPROVED PROCESS OF PRODUCING POLYCARBOXY PENDANT POLYCARBONAMIDE POLYMERS SUITABLE FOR CYCLIZATION INTO POLYIMIDES BY FORMING A DISPERSION OF EACH REACTANT, THAT IS, A TETRACARBOXYLIC ACID (OR A CORRESPONDING MONO OR DIANHYDRIDE) AND A DIAMINE RESPECTIVELY, IN AN INERT SUBSTANTIALLY NON-POLAR, ORGANIC SUBSTANTIALLY ANHYDROUS LIQUID; AND THEN ADDING A POLAR ORGANIC SOLVENT SLOWLY TO THE DISPERSION EITHER CONTINUOUSLY OR INTERMITTENTLY, WITH STIRRING AND APPROPIATE HEAT CONTROL, WHEREBY SAID REACTANTS REACT TO FORM SAID POLYCARBOXYL PENDANT POLYCARBONAMIDE.

Abstract: PROCESS FOR PREPARING POLYMIDES CONTAINING UNITS HAVING THE FOLLOWING FORMULA:
(-OC-(-)N-OC-)>R
WHEREIN R AND R'' EACH REPRESENTS AT LEAST ONE ALIPHATIC, AROMATIC OR CYCLOALIPHATIC RADICAL WHICH MAY BE SUBSTITUTED AND WHICH MAY CONTAIN HETERO ATOMS COMPRISING REACTING A DICARBOXYLIC ACID DIAZIDE HAVING THE FORMULA:
N3-CO-R''-CO-N3
WHEREIN R'' HAS THE SAME MEANING AS GIVEN ABOVE WITH A TETRACARBOXYLIC ACID DIANHYDRIDE HAVING THE FORMULA:
(CO-O-CO-)>R
WHEREIN R HAS THE SAME MEANING AS GIVEN ABOVE, AT A TEMPERATURE OF FROM 0 TO 300*C. THE ADHESIVE COMPOSITIONS MAY CONTAIN MINOR AMOUNTS OF ADJUVANTS SUCH AS INERT FILLERS OR EXTENDERS, METHYL CELLULOSE, POTASSIUM TRIPOLYPHOSPHATE, SODIUM ACETATE AND MIXTURES THEREOF.
