Abstract: A thermoplastic molding composition having little intrinsic color is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer, upon which is grafted a vinylaromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer. The thermoplastic polymer is a copolymer of a vinylaromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of intrinsic color coupled with good mechanical properties and can be processed by, for example, extrusion, injection molding, calendaring, blow molding, compression molding, or sintering.

Abstract: A rubber elastic block copolymer has at least one block A made of polymerised units of a vinyl aromatic monomer that forms a hard phase and/or a block B with diene monomers that forms a first rubber elastic (soft) phase, and at least one elastomer block B/A with polymerised units of both a vinyl aromatic monomer and a diene that forms if required a second or additional soft phase. The glass transition temperature Tg of block A is higher than 25 ~C and that of blocks B or B/A is lower than 25 ~C. The phase volume ratio between blocks A and B/A is selected so that the hard phase represents 1 - 40 % by volume of the total block copolymer and the diene amounts to less than 50 % by weight.
