Curable linear polyesters
Abstract
Abstract CURABLE POLYESTERS CONTAINING AN ADAMANTANE MOIETY ARE PREPARED IN ONE- OR TWO-STAGE CONDENSATION TYPE REACTIONS. THE POLYESTERS ARE PREPARED FROM A HYDROCARBON SUBSTITUTED ADAMANTANE DIOL AND ANHYDRIDE OF UNSATURATED DIACIDS SUCH AS MALEIC ACID ALONE OR WITH A SECOND DIOL SUCH AS ETHYLENE GLYCOL. IN ADDITION TO THE ANHYDRIDES OF UNSATURATED DIACIDS, THE POLYESTER CAN CONTAIN SATURATED DIACID MOIETIES. THE POLYESTERS SO PREPARED CAN BE CROSSLINKED WITH A CONVENTIONAL CROSSLINKING AGENT AND CURABLE POLYMER CAN BE CAST INTO SHEETS OR FILMS AND CURED. THE CURABLE BLEND CAN BE USED AS A COATING AND CURED IN PLACE TO GIVE CHEMICAL-RESISTANT SURFACES. THE CROSSLINKED POLYMERS EXHIBIT EXTREMELY GOOD HYDROLYTIC AND SOLVENT STABILITY WITH GOOD HEAT AND ULTRAVIOLET STABILITY.
