PROCESS WHICH COMPRISES DISSOLVING ABOUT 5 TO 50% BY WEIGHT OF A COPOLYMER OF ABOUT 10-60% BY WEIGHT OF A POLYMERIZABLE MONO-OLEFIN AROMATIC COMPOUND SESELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS AND CHLOROSTYRENES, AND ABOUT 90-40% OF A MONO-OLEFIN OF 2 TO 8 CARBON ATOMS, HAVING AN INTRINSIC VISCOSITY ABOVE 0.5 AND HAVING AN IODINE NUMBER LESS THAN 10, IN 50 TO 95% BY WEIGHT OF A COMPATIBLE HEAT POLYMERIAZABLE MONOMER COMPRISING AT LEAST 74% BY WEIGHT OF AN UNSATURATED ALIPHATIC COMPOUND SELECTED FROM THE GROUP CONSISTING THEN HEATING THE RESULTANT MIXTURE AT ABOUT 20* -125* C. TO EFFECT POLYMERIZATION OF SAID HEAT-POLYMERIZABLE MONOMER IN SITU IN THE PRESENCE OF SAID AROMATIC-OLEFIN COPOLYMER.
