  • Patent number: 4529767
    Abstract: A thermosetting latex paint is disclosed which cures to provide better gloss and gloss retention of ultraviolet exposure. This latex paint comprises water having suspended therein copolymer particles of aqueous emulsion copolymerized monomers consisting essentially of monoethylenically unsaturated monomers including at least about 30% up to about 80% of vinyl acetate, the balance of the monomers in the copolymer including from 2% up to about 15% of monomers providing reactive hydrogen atoms, like hydroxyethyl methacrylate, to enable the copolymer to thermoset in the presence of a curing agent which reacts with the reactive hydrogen atoms of the copolymer, like hexamethoxymethyl melamine. The copolymer particles are suspended in the water by surfactant comprising at least 2% up to about 8%, based on total monomers, of an ethylene oxide adduct of an alkyl-substituted phenol having from 10-18 carbon atoms in the alkyl group with 5-14 moles of adducted ethylene oxide per mole of said substituted phenol.

  • Patent number: 4396698
    Abstract: A loaded polymer latex composition is disclosed. The composition comprises an aqueous polymer latex whose dispersed phase is made up of a specified cross-linked quaternary salt polymer loaded with a specified hydrophobic substance. The latex composition can be advantageously employed as a mordant polymer in a photographic element for a color diffusion transfer process. Use of the latex improves light resistance without lowering the maximum densities of the film images.

  • Patent number: 4332760
    Abstract: A method of preparing oil-extended elastomer and shoe sole compound as an integral part of the anionic polymerization process for making elastomer is presented. The method eliminates the step of isolating the neat elastomer and of reheating the elastomer to compound it into the final product.
