Abstract
An additive mixture containing a dibenzoate and either or both of a compound containing at least one structural unit and a compound containing at least one structural unit is disclosed. The additive combination enhances the processability of a thermoplastic molding composition that contains a (co)polymer of styrene, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride and N-substituted maleimide and a graft copolymer.
Claims13
A thermoplastic molding composition comprising
- A) from 5 to 95 wt. % of one or more thermoplastic (co)polymer of at least one member selected from the group consisting of styrene, α-methylstyrene, styrene substituted at the nucleus, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride and N-substituted maleimide,
- B) from 5 to 95 wt. % of one or more graft polymers of
- B.1) from 5 to 90 parts by weight of at least one member selected from the group consisting of styrene, a-methylstyrene, styrene substituted at the nucleus, methyl methacrylate, acrylonitrile, methacrylonitrile, maleic anhydride and N-substituted maleimide, with
- B.2) from 95 to 10 parts by weight of at least one rubber having a glass transition temperature ≦10° and
- C) from 0.5 to 10 parts by weight (per 100 parts by weight of A)+B)) of a mixture of a) at least one dibenzoate of di- or tri-alkylene glycols and at least one of b) and c) wherein b) is at least one compound containing at least one structural unit
- and c) is at least one compound containing at least one structural unit
A mixture comprising a) at least one dibenzoate of di- or tri-alkylene glycols and at least one of b) and c) wherein b) is at least one compound containing at least one structural unit
- and c) is at least one compound containing at least one structural unit
