The core component is made of a water-soluble polymer, in particular a polyvinyl alcohol. The coating component is a water-soluble or water-insoluble substance which is applied to the water-moistened particles of the core component. The particles of the polymer granulate have diameters within the range from 0.6 to 6 mm. The granulate has particularly good freeflowing properties; it is especially suitable for preparing adhesives.Type: GrantFiled: July 30, 1985Date of Patent: November 14, 1989Assignee: Hoechst AktiengesellschaftInventors: Wolfgang Zimmermann, Albrecht Harreus

Patent number: 4879321Abstract: 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.degree.

Patent number: 4795801Abstract: The invention relates to the use of chemical grafting to produce a stable liquid composition that is capable of hardening following an optional polymerization process. Under the invention, in order to produce a composition that is liquid, at least initially and prior to any polymerization, a polymerizable organic acid comprising at least two double bonds in resonance is combined in a solvent with an inorganic filler having at least one hydroxylated group with the help of a catalyst acting as a radical upon said organic acid. By adjusting the concentration of catalyst and using a polymerizable monomer solvent, the liquid composition may be hardened by polymerization after the initial grafting reaction. By ensuring that a portion of the organic acid retains free bonds that have not combined with filler, it is also possible to induce the composition to become chemically attached to a resin or to reinforcing fibers. The invention may be applied to the production of molded objects.Type: GrantFiled: February 9, 1987Date of Patent: January 3, 1989Inventors: Herve M. J. Farge, Jean M. L. Farge

Patent number: 4728678Abstract: The invention relates to a process for the grafting of unsaturated monomers to the surface of glass substrates. The process comprises applying to the glass substrates a solution comprising a silane having a double ethylene bond, contacting the products thus coated with an atmosphere formed by a mixture of ozone and oxygen, and placing these coated products in contact with an unsaturated organic monomer. The monomer may be added in the form of a solution, an emulsion or a suspension. The products thus obtained may have a number of technical applications.Type: GrantFiled: November 28, 1986Date of Patent: March 1, 1988Assignee: Saint-Gobain RechercheInventors: Roger Chatelin, Louis Gavet
