Claims
- 1. A method of forming a polymeric matrix containing inorganic filler material, comprising:
- (a) adhering a layer of fixing agent to the surface of filler material;
- (b) fixing catalyst to the surface of filler material to provide catalyst-bearing filler material by adsorbing the catalyst in the layer of fixing agent;
- (c) bringing together the catalyst-bearing filler material and polymerizable material; and
- (d) polymerizing the polymerizable material, under conditions effective therefor, to form the polymeric matrix.
- 2. The method according to claim 1, wherein the fixing agent is an organo-metallic compound.
- 3. The method according to claim 2, wherein the organo-metallic compound is selected from the group consisting of silanes, chromium complexes, titanium derivatives, and polymers having a methoxysilyl group.
- 4. The method according to claim 1, wherein the filler material is contacted with a solution containing the catalyst and a fixing agent in order to fix the catalyst to the surface of the filler material in step (a), and the catalyst-bearing filler material is then dried.
- 5. The method according to claim 1, wherein the filler material is contacted with a suspension containing the catalyst and a fixing agent in order to fix the catalyst to the surface of the filler material in step (a).
- 6. The method according to claim 1, wherein the polymerizable material is an unsaturated polyester.
- 7. The method according to claim 6, wherein the catalyst is a peroxide.
- 8. The method according to claim 1, wherein the filler material comprises vitreous material.
- 9. The method according to claim 8, wherein the filler material comprises vitreous beads.
- 10. The method according to claim 9, wherein the vitreous beads comprise solid beads.
- 11. The method according to claim 9, wherein the vitreous beads are selected so that they have a median diameter ranging between 20 and 650 micrometers inclusive.
- 12. The method according to claim 9, wherein at least some of the vitreous beads are treated with an etching medium prior to coating.
- 13. The method according to claim 12, wherein the etching medium used contains fluorine ions.
- 14. The method according to claim 9, further comprising coating vitreous beads with a material which renders them both oleophobic and hydrophobic to provide coated beads, and incorporating the coated beads into the filler material together with catalyst-bearing vitreous beads.
- 15. The method according to claim 14, wherein the catalyst-bearing vitreous beads are incorporated into the filler material in a proportion ranging between 70% and 90% by weight of the total filler.
- 16. The method according to claim 8, wherein the filler material comprises glass fibers.
- 17. The method according to claim 9, further comprising applying the polymerizable material to a pavement, and bringing together the polymerizable material and the catalyst-bearing vitreous beads by applying the catalyst-bearing vitreous beads onto the polymerizable material to cause in situ polymerization thereof and the formation of a pavement marking.
- 18. The method according to claim 1, further comprising shaping the polymerizable material after step (c) before hardening thereof by polymerization in step (d).
- 19. The method according to claim 16, wherein the filler material is glass fiber matting which is woven or unwoven and which is laid up, and wherein the a polymerizable material is applied to catalyst-bearing matting in step (c).
- 20. A filled polymeric matrix formed by a method according to claim 1.
