    • A method is disclosed for the production of low-emission moulded pieces for continuous use at temperatures > 50 °C, made from a thermoplastic moulded mass containing A) 10 to 99.9 wt.% polybutylene terephthalate or mixtures thereof with polyethylene terephthalate and/or polypropylene terephthalate, B) 0.1 to 50 wt.% of at least one terpolymer, obtained from b1) at least one vinylaromatic monomer, b2) at least one C1 to C4 alkyl(meth)acrylate or (meth)acrylonitrile and b3) 0.1 to 10 wt.%, based on total weight of components b1) to b3), of at least one monomer, containing an alpha,ß-unsaturated anhydride and C) 0 to 60 wt.% of further adjuncts, the sum of the weight percentages of components (A) to (C) being 100 %, by injection moulding, characterised in that the injection moulding is carried out using a degassing plastifier unit with a housing having a feed opening for the thermoplastic moulding mass, a screw, transporting and plastifying the thermoplastic moulding mass along a screw path and one or more degassing openings for the escape of volatile components from the plastified thermoplastic moulding mass in the screw path to the outside from the degassing plastifier unit.
    • 公开了一种用于生产在温度> 50℃下连续使用的低排放模制件的方法,由含有A)10至99.9重量%的聚对苯二甲酸丁二醇酯或其与聚对苯二甲酸乙二醇酯和/或聚丙烯的混合物的热塑性模塑料制成 对苯二甲酸酯,B)0.1〜50重量%的由b1)至少一种乙烯基芳族单体得到的至少一种三元共聚物,b2)至少一种(甲基)丙烯酸C1〜C4烷基酯或(甲基)丙烯腈和b3)0.1〜10 至少一种含有α,β-不饱和酸酐的单体的重量%,基于组分b1)至b3)的总重量,C)0至60重量%的另外的助剂,其重量百分数之和 组分(A)至(C)为100%,其特征在于,使用具有用于热塑性成型体的进料口的壳体的脱气增塑器单元进行注射成型,螺杆,输送和塑化 沿着螺丝的热塑性成型体 路径和一个或多个脱气开口,用于将挥发性组分从螺旋路径中的塑化的热塑性模塑料料从脱气增塑器单元逸出到外部。
