Polyester-vinyl monomer compositions containing hydrogen peroxide

Claim 1

A PROCESS WHICH COMPRISES COPOLYMERIZING AN UNSATURATED POLYESTER RESIN PREPARED BY REACTING A POLYHYDRIC ALCOHOL WITH A MEMBER OF THE GROUP CONSISTING OF ALPHA, BETA ETHYLENICALLY UNSATURATED DICARBOXYLIC ACIDS AND ANHYDRIDES THEREOF, WITH A LIQUID MONOMER CONTAINING A CH2=C< GROUP IN ADMIXTURE WITH O.1 TO 5 PERCENT BASED ON THE COMBINED WEIGHT OF SAID POLYESTER AND MONOMER, OF A PEROXIDE POLYMERIZATION CATALYST COMPRISING A HYDROGEN PEROXIDE SOLUTION CONTAINING ABOUT 10 TO 50 PERCENT BY WEIGHT OF H2O2 IN A SOLVENT SELECTED FROM THE GROUP CONSISTING OF ETHERS WHOSE OXYGEN-LINKED HYDROCARBON GROUPS ARE UNINTERRUPTED HYDROCARBON CHAINS OF NOT MORE THAN 4 CARBON ATOMS, ESTERS OF LOWER ALIPHATIC ALCOHILS, AND ESTERS OF ETHER ALCOHOLS, THE OXCYGEN-LINKED HYDROCARBON GROUPS OF SAID ETHER ALCOHOLS BEING UNINTERRUPTED HYDROCARBON CHAINS HAVING NOT MORE THAN 4 CARBON ATOMS, BOTH SAID ESTERS OF SAID ALCOHOLS AND SAID ETHER ALCOHOLS BEING ESTERS OF AN ACID SELECTED FROM THE GROUP CONSISTING OF ALIPHATIC MONOCARBOXYLIC ACIDS CONTAINING 1-4 ATOMS, ALIPHATIC DICARBOYXLIC ACIDS, ALICYCLIC AND AROMATIC CARBOXYLIC ACIDS, PHOSPHORIC ACID, CARBONIC ACID, AND MIXTURES THEREOF, SAID MONOMER BEING SUBSTANTIALLY THE ONLY SOLVENT FOR SAID POLYESTER RESIN.
