Claims
- 1. A polymeric article comprising a synthetic polymer matrix and a filler material, the synthetic polymer matrix being comprised of a synthetic polymer selected from the group consisting of polyamide, polystyrenes, epoxy resins, and polyester resins, and the filler material being comprised of glass beads bearing coatings of at least one coating agent which comprises a fluorocarbon compound, in a total coating amount not exceeding 1% by weight based on the weight of uncoated glass 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.
- 2. An article according to claim 1, wherein said fluorocarbon compound is an anionic fluorocarbon compound.
- 3. An article according to claim 2, wherein said fluorocarbon compound is a fluoro-alkyl-sulphonate.
- 4. Formable polymeric material comprising a synthetic polymer and a filler material, the synthetic polymer being selected from the group consisting of polyamides, polystyrenes, epoxy resins, epoxy resin-polyamine mixtures, and polyester resins, and the filler material being comprised of glass beads bearing coatings of at least one coating agent which comprises a fluorocarbon compound, in a total coating amount not exceeding 1% by weight based on the weight of uncoated glass beads, which coatings limit adhesion between the glass beads and the synthetic polymer and confer an increased impact resistance on an article formed from such filled polymeric material as compared with an article which includes uncoated glass beads as filler material but is otherwise identical.
