Production of ABS molding material, involves polymerization of monomers in rubber solution made by polymerizing diolefin in styrene with catalyst containing rare earth metal and organo-aluminium compounds

摘要

A process for the production of ABS molding materials involves polymerization in the presence of a rubber solution which is obtained by polymerisation of diolefins in a solution of vinylaromatic monomers in the presence of a catalyst containing: (A) rare earth metal compound(s); (B) organo-aluminium compound(s); and (C) optionally a Lewis acid. An Independent claim is also included for ABS molding materials obtained by this process.
