    摘要: Molding compositions having improved properties for low-pressure, low-shear molding techniques are prepared by carrying out a two-stage polymerization of an initial mixture comprising a polymerizable monomer selected from the group consisting of (1) a polymerizable aromatic monoalkenyl monomer or (2) a mixture of such aromatic monoalkenyl monomer with another polymerizable monovinyl monomer; in the presence of a butadiene rubber elastomer under bulk polymerization conditions, followed by suspension polymerization conditions; the process being characterized by the incorporation into the initial mixture of 1 to 10 wt. %, based on the polymerizable monomers, of a straight chain saturated polyester having an average molecular weight of 1,000 to 50,000.

    摘要: A new impact-resistant ABS resin composition is disclosed comprising (1) 100 parts by weight of a graft copolymer of vinyl aromatic monomer and vinyl cyanide monomer, said copolymer being grafted onto butadiene rubber particles of a size of from 0.5 to 2.0 .mu. dispersed in the graft copolymer and (2) 1 to 10 parts by weight of a straight chain saturated polyester having an average molecular weight of from 1000 to 50000. The composition is prepared by the bulk-suspension two stage polymerization of vinyl aromatic monomer and vinyl cyanide monomer in the presence of butadiene rubber component. The polyester is incorporated during either the bulk polymerization stage or the suspension polymerization stage, or it is blended with the ABS polymer after the two stage polymerization is completed.
