109 words
THE METHOD OF COPOLYMERIZING A MIXTURE CONSISTING OF 1) 10 TO 90 PARTS OF A CONJUGATED ETHYLENICALLY UNSATURATED COMPOUND OF THE CLASS CONSISTING OF DRYING OILS, DRYING OIL ACIDS, AND ROSIN AND 2) 90 TO 10 PARTS OF A POLYMERIZABLE UNSATURATED COMPOUND OF THE CLASS CONSISTING OF STYRENE, ACRYLONITRILE, METHYL METHACRYLATE, ISOPRENE AND CYCLOPENTADIENE, WHICH CONSISTS IN HEATING THE MIXTURE OF 1) AND 2) AT A TEMPERATURE OF 35* TO 300* C. IN THE PRESENCE OF A PEROXIDE CATALYST AND FROM 0.5 TO 5%, BASED ON A POLYMERIZABLE UNSATURATED COMPOUND, OF AN ALKYL MERCAPTAN HAVING AT LEAST FOUR CARBON ATOMS, AND IN THE ABSENCE OF WATER AND ORGANIC SOLVENTS.
