GRAFT POLYMERIZATION OF STYRENE MONOMER AND MIXED MONOMER OF STYRENE AND ACRYLONITRILE ON TO ACRYLONITRILE-BUTADIENE COPOLYMER (in Japanese)
Graft polymerization of styrene monomer and a mixed monomer of styrene and acrylonitrile onto an actylonitrilebuthdiene copolymer was conducted by both radiation and a chemical catalyst method. In the experiments, the radiation method used a direct process by which gamma radation was applied to a uniform solution, and the catalyst method adopted a solution polymerization process that involved as much the same conditions as possible of the radiation method. Where styrene monomer alone was used, the radiation method proved better than the catalyst method from the results of both tensile and impact tests. Moreover, the former process produced less gel. However, where a mixed monomer of styrene and acrylonitrile was used, both methods indicated no appreciable difference in the mechanical properties of product. In the last analysis, the radation grafting method seemed to be more effective than the chemical catalyst method, even where the trunk polymer has a double bond. (P.C.H.)
