Claim 1
Independent Claim
122 words
A METHOD OF PRODUCING A POLYMERIZABLE RESINOUS COMPOSITION WHICH REMAINS STABLE AT AMBIENT TEMPERATURES AND RETAINS A MOLDABLE CONSISTENCY BUT CAN BE HARDENED AND SET BY HEAT AND PRESSURE WHICH COMPRISES DISSOLVING A CROSS-LINKABLE, UNSATURATED POLYESTER RESIN IN A VINYLIDENE MONOMER SOLVENT COPOLYMERIZABLE WITH SAID ESTER, THE SAID SOLVENT COMPRISING FROM ABOUT 10% TO ABOUT 60% OF THE TOTAL WEIGHT OF THE SOLUTION, ADDING THERETO FROM ABOUT 1% TO ABOUT 2% BY WEIGHT OF BENZOYL PEROXIDE, FROM ABOUT 0.05% TO ABOUT 0.3% BY WEIGHT OF STANNOUS CHLORIDE AND FROM ABOUT 0.025% TO ABOUT 1% BY WEIGHT OF 4-METHYL-2,6-DI-TERTIARY BUTYLPHENOL, ADMIXING SAID INGREDIENTS WHILE MAINTAINING THE TEMPERATURE AT FROM ABOUT 10*C. TO ABOUT 80*C. UNTIL A MOLDABLE MASS OF GEL-LIKE CONSISTENCY IS OBTAINED.
