  • Patent number: 4461848
    Abstract: An improved process for the manufacture of vesiculated beads has been developed which can be used for the production of semi-gloss or satin finished paints. The process involves mixing an oil-phase containing a cross-linkable polyester resin in solution with a monomer co-polymerizable with the resin and an aqueous phase containing an emulsifying agent under conditions such that globules of the oil-phase are formed having a diameter of less than 1.5 microns. The emulsion containing the globules also contains a base and the amount of the emulsifying agent is from 3 to 16 grams per 100 ml of the oil-phase and the volume fraction has a value of 0.2 to 0.4 and X as defined is from 4 to 8. Preferably the beads are pigmented with titanium dioxide pigment.

  • Patent number: 4363888
    Abstract: A process for the preparation of rigid beads, of cross-linked polyester resin which beads may be solid or vesiculated, by forming an oil-in-water or a water-in-oil-in-water emulsion in which the oil phase contains an unsaturated polyester resin and an unsaturated organic monomer to provide said cross-linking and thereafter heating the emulsion to a temperature of at least 45.degree. C. before initiating polymerization of the oil phase by the introduction into the system of a polymerization initiator, and promoter system, if the latter is not already present in the emulsion.

    Abstract: An aqueous sizing composition, glass fiber strands having the dried residue of the aqueous sizing composition and processes for producing these articles are provided that enable the production of glass fiber reinforced polymeric materials having improved properties. In addition, improvements are obtained in the processability of using glass fiber roving in the production of sheet molding compound, bulk molding compound and thick molding compound. The sizing composition, sized glass fiber strands, processes, reinforced polymeric materials and improvements of this invention emanate from the use of epoxidized polar thermoplastic copolymers in aqueous sizing compositions that are substantially insoluble in the matrix polymer. The aqueous sizing composition has one or more cross-linkable film formers, one or more organosilane coupling agents and about 3 to about 12 weight percent of the aqueous sizing composition of the epoxidized polar thermoplastic copolymer.

  • Patent number: 4321332
    Abstract: This invention relates to a process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter. Previously-known processes for the preparation of granules of this type have utilized polyamines; this has led to odor and color problems. These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used, the pKa value of the conjugate acid of the anion is greater than 2. The resulting granules are useful at matting and opacifying agents in, for example, paint compositions.
