Compounding aids for thermosetting allylic resin molding compounds
Abstract
Abstract THE COMPOUNDING CHARACTERISTICS OF THEMOSETTING ALLYLIC RESIN MOLDING COMPOUNDS ARE IMPROVED BY THE ADDITION OF 1 TO 100 PARTS PER MILLION, BY WEIGHT BASED ON RESIN, OF A METAL, IN CHEMICALLY COMBINED FORM, SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM, POTASSIUM, CALCIUM, VANADIUM, CHROMIUM, MANGANESE, IRON, COBALT, NICKEL, COPPER, ZINC, ZIRCONIUM, MOLYBDENUM, ANTIMONY, TUNGSTEN, LEAD AND CERIUM. ADDITION OF AN EFFECTIVE AMOUNT OF THESE SELECTED METALS CAUSES A SUBSTANTIAL IMPROVEMENT IN COMPOUNDING PERFORMANCE IN TERMS OF CONTROLLABLE UNIFORM RATE OF VISCOSITY INCREASE DURING COMPOUNDING AND ELIMINATION OF STICKING TO COMPOUNDNG EQUIPMENT WITHOUT SUBSTANTIALLY ALTERING THE PROPERTIES OF THE MOLDING COMPOUND OR THE FINAL MOLDED PRODUCT.
