摘要
In or for a polymeric article incorporating a synthetic polymer and a filler material, which filler material includes glass beads bearing coatings of at least one coating agent in a total coating amount not exceeding 1% and preferably between 0.02% and 0.2%, by weight based on the weight of uncoated beads, which coatings limit adhesion between the glass beads and the synthetic polymer and confer an increased impact resistance on the article as compared with an article which includes uncoated glass beads as filler material but is otherwise identical. Preferred coating materials include silanes, fluorocarbon compounds and synthetic polymers having shockabsorbing properties, especially synthetic polymers having a glass transition temperature (Tg), determined by differential scanning calorimetry, which is lower than 15 DEG C.
