First Claim
Patent Images
1. THE POLOYLEFIN DEGRADATION PROCESS WHICH COMPRISES MIXING WITH A CRYSTALLINE POLYOLEFIN FROM 0.75% TO 10% BY WEIGHT OF A METAL SALT OF A CARBOXYLIC ACID AND HEATING THE RESULTANT MIXTURE IN AN ATMOSPHERE SUBSTANTIALLY FREE OF OXYGEN TO A TEMPERATURE WITHIN THE RANGE OF FROM 275*C. TO 450*C. TO PRODUCE A POLYMER HAVING AN APPRECIABLY LOWER MOLECULAR WEIGHT THAN THE STARTING POLYOLEFIN.
