Abstract: General purpose inherently tacky acrylic pressure sensitive adhesive polymers formed of alkyl acrylates, vinyl esters, diesters of dicarboxylic acid and saturated carbocylic acids, having improved properties, a lower residual monomer content and a reduced polymerization time are formed by a sequential polymerization process in which 50 to 95 percent, typically 90 percent, of the monomers are incrementally added to a reactor as a first charge containing substantially all of the vinyl esters, preferably all of the diesters of dicarboxylic acid, the balance of the monomers being fed in a second incremental charge.

Abstract: General purpose inherently tacky acrylic pressure sensitive adhesive polymers formed of alkyl acrylates, vinyl esters, and saturated carboxylic acids, having improved properties, a lower residual monomer content are formed by a sequential emulsion polymerization process in which 40 to 70 percent, typically 45 percent, of the monomers are incrementally added to a reactor as a first charge containing substantially all of the vinyl esters, the balance of the monomers being fed in a second incremental charge.

Abstract: A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.

Abstract: Versatile coalescing agents for water-borne coating applications are disclosed. The coalescents comprise propoxylated propylene glycol tert-butyl ether and one or more organic solvents, particularly glycol ethers. These coalescents efficiently reduce minimum film-forming temperature, and also have a dramatically reduced tendency to swell resins compared with prior art coalescents.

Abstract: Disclosed herein is an improved vinyl chloride latex copolymer composition having good color stability, characterized in that it contains a small but effective amount of an alpha-olefin to provide color stability of films of the composition.

Abstract: A fluorine containing polymer containing ester groups in the backbone of the polymer is prepared by the ring opening free radical polymerization of a cyclic ketene acetal with a vinyl monomer component comprising a fluorine containing vinyl monomer. The aforesaid fluorine containing polymer which contains ester groups can be reacted with a material containing functional groups capable of cleaving the carbon oxygen single bonds of the ester groups. The resultant oligomeric material contains functionality as a result of the cleavage which is suitable for reaction with a crosslinking agent to form a cured film.
