Process for the preparation of polybutadiene grafted with styrene and acrylonitrile and having a very low end content of unreacted residual monomers |
摘要 |
During the reaction of grafting of styrene and acrylonitrile to polybutadiene, the conversion of the graft monomers is increased from the values of 92 DIVIDED 94% usually obtained, to values very close to 98%, by carrying out a redox-type reaction additional to that provided by the process, in the presence of an additional aliquot of acrylonitrile and of catalytic system.
