Abstract: Coating compositions comprising hydroxy functional film formers, crosslinking agent therefor and a novel flow control additive. Flow control additive comprises stable crosslinked dispersion formed by addition polymerization of selected monomers in the presence of (i) organic liquid which is a solvent for the monomers, but a non-solvent for the polymer and (ii) polymeric dispersion stabilizer having solvated and non-solvated segments, wherein the dispersion is stabilized further by inclusion therein of a butylated melamine formaldehyde resin.

Abstract: Disclosed are novel organic pigments adapted particularly for use as fillers for paper. The organic pigments are finely divided particles obtained by graft copolymerizing an ethylenically unsaturated monomer, such as styrene, onto a water-soluble cationic prepolymer in an aqueous solution and in the presence of a free-radical polymerization initiator.

Abstract: A method for producing latices of copolymers of butyl acrylate and 1-methyacrylate-1-tert-butyl peroxy ethane resides in the emulsion copolymerization of butyl acrylate and 1-methacrylate-1-tert-butyl peroxy ethane carried out by prepolymerizing of butyl acrylate up to a conversion degree of 90-100% followed by introducing 1-methacrylate-1-tert-butyl peroxy ethane into the reaction mass. For a redox system, use is made of potassium persulfate and sodium metabisulfate.

Abstract: An improved photosensitive resin system being essentially solvent-free which contains an ester produced from an unsaturated organic acid and a polyhydroxyl containing material, a photoinitiator, a carbonyl initiator, and a monomer capable of reacting with an acrylic monomer, wherein an improvement comprises an additional component comprising an unsaturated hydroxyl containing polymer hydrocarbon. The improved composition has curing rates far in excess of those systems not using the hydroxyl containing unsaturated polymer. In particular, the advantages obtained through the use of the additional component are much faster curing of the composition, exceptional gloss, toughness, abrasion resistance and good rub resistance.

Abstract: A graft copolymer is obtained by graft-polymerizing an ethylenically unsaturated monomer onto a rubber trunk polymer which is a copolymer of a polyalkylene oxide monomer comprising 4 to 500 alkylene oxide groups together with an ethylenic unsaturation, and a conjugated diene and/or an alkyl acrylate. By adding an anionic surfactant to a base resin which comprises this graft copolymer alone or a mixture of this graft copolymer and another thermoplastic resin, an antistatic resin composition can be obtained. The resin composition thus obtained possesses excellent and permanent antistatic property that is not lowered by washing or wiping as is the case with conventional antistatic resins comprising an antistatic agent.

Abstract: Polymers of esters of acrylic acid having an average chain length of about 6 to about 30 mers are prepared by an anionic polymerization reaction, carried out in the presence of a catalytic amount of an alkoxide anion. These polymers, their hydrolysis products, and their derivatives have a wide variety of applications, including among others use as components in films, coatings, fibers, impregnants, adhesives, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.
