Abstract
A METHOD FOR MAKING LOW DENSITY (12.8-17.6KG/M3(0.8-1.1 IB/CU.FT)) EXPANDED POLYMERIC PRODUCTS USES BLOWING AGENT IN AN AMOUNT OF ONLY FROM 2 TO 4.4 WEIGHT PERCENT. THE PROCESS USES 2 TO 5 EXPANSION STEPS TOGETHER WITH A POLYMER HAVING A PARTICULAR POLYDISPERSITY, WEIGHT AVERAGE MOLECULAR WEIGHT AND MZ:MN, THIS POLYMER HAVING A GREATER EXPANDABILITY THAN CONVENTIONAL POLYMERS. THE PROCESS REQUIRES ONLY ABOUT HALF OF THE AMOUNT OF BLOWING AGENT CURRENTLY BEING USED IN COMMERCIALLY VIABLE PROCESSES FOR MAKING EXPANDED POLYSTYRENE PRODUCTS. THE PROCESS CAN BE USED WITH OR WITHOUT A MOLDING STEP.
