摘要:
Graft copolymers (P1) contain, in any desired sequence, at least (P1.1) a hard segment having a glass transition temperature of at least 11.degree. C., which contains at least one vinylaromatic monomer as the monomer or as one of two or more monomers copolymerizable with one another and a crosslinker component comprising at least dihydrodicyclopentadienyl acrylate as a crosslinking agent having two or more functional groups of different reactivity and at least one crosslinking agent having two or more functional groups of the same reactivity, and (P1.2) a soft segment having a glass transition temperature of not more than 10.degree. C., which contains at least one acrylate as the monomer or as one of two or more monomers copolymerizable with one another, and blends and thermoplastic materials contain said graft copolymers.
摘要:
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.
