| 摘要 |
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 good 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.
