摘要： An unsaturated polyester prepared by reacting under esterification conditions the following reactants; A. AN ETHYLENICALLY UNSATURATED DICARBOXYLIC ACID; B. TETRAHYDROPHTHALIC ANHYDRIDE OR ENDOMETHYLENE TETRAHYDROPHTHALIC ANHYDRIDE; C. AN ALIPHATIC SATURATED DICARBOXYLIC ACID OR A DIMER OR TRIMER OF AN ETHYLENICALLY UNSATURATED ALIPHATIC MONOCARBOXYLIC ACID; AND D. CYCLOHEXANEDIMETHANOL OR A MIXTURE OF NEOPENTYL GLYCOL AND A SECOND DIHYDRIC ALCOHOL. Upon crosslinking or curing the unsaturated polyester with a vinyl monomeric crosslinking agent, there can be obtained products having improved thermal stability properties.

摘要： INHIBITORS, SUCH AS, PHENAZINE ARE ADDED TO UNCURED POLYESTER RESIN SYSTEMS TO PREVENT GELATION OF THOSE SYSTEMS WHEN THEY ARE STORED AT ROOM TEMPERATURE OR A ELEVATED TEMPERATURE FOR PERIODS OF TIME IN EXCESS OF THREE YEARS. BETWEEN 0.5 AND 1.0 MOLE PERCENT INHIBITOR IS ADDED TO THE UNCURED POLYESTER SYSTEMS.
