This invention relates to thermoplastic molding compositions, particularly thermoplastic polyesters, having incorporated therein a fluorinated polyolefin to improve wear resistance. More particularly, disclosed are polyester compositions having improved wear resistant properties comprising a polyester resin, most preferably a poly(butylene terephalate) resin; a fluorinated polyolefin compound and a hindered phenolic compound and an ester compound, the last two components serving as a migrator package that serves to push a disproportionate amount of the fluorinated polyolefin within the subsurface of the resulting composition to thereby augment the wear resistant effect of the fluorinated polyolefin.
本发明涉及热塑性成型组合物,特别是热塑性聚酯,其中加入了氟化聚烯烃以提高耐磨性。更具体地说,本发明公开了具有更好耐磨性能的聚酯组合物,该组合物包括聚酯树脂,最好是聚对苯二甲酸丁二醇酯树脂;氟化聚烯烃化合物和受阻酚醛化合物及酯类化合物,后两种成分可作为迁移包,用于将不成比例的氟化聚烯烃推入所得组合物的次表层,从而增强氟化聚烯烃的耐磨效果。
