Claim 1
Independent Claim
54 words
A METHOD FOR PREPARING A SOLID HIGH MOLECULAR WEIGHT POLYMER WHICH COMPRISES POLYMERIZING A HALOGEN-SUBSTITUTED OLEFIN HAVING 2 CARBON ATOMS IN THE PRESENCE OF A COMPLETELY HALOGENSUBSTITUTED ACETYL PEROXIDE AT A SUFFICIENTLY LOW TEMPERATURE TO REGULATE THE DECOMPOSITION OF SAID PEROXIDE AND CONTINUING THE POLYMERIZATION UNTIL A SOLID HIGH MOLECULAR WEIGHT POLYMER IS PRODUCED.
