| abstract |
THERMOSETTING MOLDING COMPOSITIONS ARE PREPARED USING POLYMERIZALE UNSATURATED POLYESTERS, POLYMERIZABLE UNSATURATED MONOMERS AND POLYMERS DERIVED FROM THE POLYMERIZATION OF A MIXTURE OF VINYL CHLORIDE AND VINYL ACETATE. FILLERS AND REINFORCING AGENTS ARE INCORPORATED IN THE COMPOSITIONS TO OBTAIN THE DESIRED PHYSICAL AND CHEMICAL PROPERTIES IN END USE APPLICATIONS. THESE COMPOSITIONS PRODUCE MOLDED ARTICLES HAVING LOW SHRINKAGE, DIMENSIONAL STABILITY AND IMPROVED SURFACE SMOOTHESS CHARACTERISTICS. |
