Method of stabilizing a polyester monomer composition with a sulphonium salt and composition thereof

Claim 1

A STORABLE LIQUID POLYESTER COMPOSITION WHICH IS STABLE AT SUBSTANTIALLY ROOM TEMPERATURE IN THE ABSENCE OF APEROXIDE CATALYST, SAID COMPOSITION CONSISTING ESSENTIALLY OF A MIXTURE OF: (A) A POLYMERIZABLE UNSATURATED ALKYD RESIN HAVING A PLURALTY OF ALPHA, BETA ETHYLENICALLY UNSATURATED GROUPS; (B) AN ETHYLENICALLY UNSATURATED MONOMER WHICH IS POLYMERIZABLE WITH SAID ALKYD RESIN; AND (C) A DISSOLVED STABILIZING AGENT SELECTED FROM THE GROUP CONSISTING OF: (1) SULPHONIUM SALTS OF ACIDS THAT HAVE AN IONIZATION CONSTANT GREATER THAN 1X10-**5; AND (2) MIXTURES OF SUCH SULPHONIUM SALT WITH A RETARDANT SELECTED FROM THE GROUP CONSISTING OF DIHYDRIC PHENOLS AND QUINONES, SAID STABILIZING AGENT SERVING: (A) TO INHIBIT POLYMERIZATION OF SAID POLYMERIZABLE COMPONENTS AT ROOM TEMPERATURE IN THE ABSENCE OF A PEROXIDE CATALYST; AND (B) TO ACCELERATE SAID POLYMERIZATION WHEN A PEROXIDE CATALYST IS ADDED TO SAID COMPOSITION.
