Abstract: Disclosed is a water-insoluble addition copolymer of an ethylenically unsaturated unsubstituted amide and at least one other ethylenically unsaturated monomer comprising sufficient amide groups mono-functionally bonded to a polyaldehyde to render the copolymer thermosettable. The copolymer is adapted for use as or for formulation in a binder. Such a binder is readily made from a copolymer latex and is useful in processes for the preparation of products such as nonwoven fabrics and bonded papers.

Abstract: This invention discloses the composition and use of salts of low molecular weight polymers of methacrylic and acrylic esters formulated with wetting, emulsifying, plasticizing or coalescing agents as aqueous finish compositions for hard surfaces. The polymers have molecular weights between 700 and 5000 and acid numbers between 50 and 275. The finishes produced by the compositions are water clear and are self-dispersible. Thus, on reapplication, the previous film is dissolved, the embedded soil removed and a fresh film left.

Abstract: An effective amount of a vinylbenzyltrialkyl ammonium salt, prepared from a vinylbenzyl halide and a tertiary amine, is polymerized with various other monomers to afford stable latex polymers which have the latex stabilizing surfactant incorporated into the polymer backbone. The use of a vinylbenzyltrialkyl ammonium salt lessens or avoids the usual problems associated with the conventional anionic, nonionic or cationic emulsifiers employed in aqueous polymerizations, that is, the latex stabilizing surfactant incorporated into the polymer backbone is the sole emulsifier. The copolymers prepared with the quaternary ammonium compounds are useful as sizing agents, as extender/binders for cationic water repellents; in addition, the polymers are depositable on pulp without requiring any deposition aids or defoamers.

Abstract: This invention relates to a latex of internally plasticized polymer particles, low in viscosity although high in hydrophilic components and film forming at temperatures below the calculated Tg of the polymer. The polymer may be prepared by a multistage emulsion polymerization process. The first stage is highly water-swellable or water-soluble. The principal second or later stage is less hydrophilic and of higher Tg than the first stage and is polymerized in the emulsion in the presence of the first stage.

Abstract: The application discloses a mixture of high molecular weight hard resins, such as polymethyl methacrylate, cellulose acetate butyrate and cellulose nitrate with low molecular weight benzoic acid terminated polyesters having a glass transition temperature in the range of -30.degree. C. to 40.degree. C. and a molecular weight in the range of 500 to 1500. The hard polyesters of this invention are obtained by the use of small diols and hard dibasic acids in addition to termination of the chain by the hardening component benzoic acid. Saturated linear dicarboxylic acids are used for less than half of the acid monomer content, on a molar basis, since these are softening components. The polyesters are used to lower the melting point and improve the flow of the high molecular weight polymers without excessively plasticizing these high molecular weight polymers to the point where they are noticeably softened at use temperatures.

Abstract: Polymers of esters of methacrylic acid having an average chain length of about 6 to about 50 mers are prepared by an anionic polymerization reaction, carried out in the presence of a chain-regulating alcohol and a catalytic amount of an alkoxide anion, in which control of the molecular weight and molecular weight distribution of the polymer are achieved by regulating the ratio of the total quantity of alcohol employed to the total monomer charge. These polymers, their hydrolysis products, and their derivatives having allyl functionality have a wide variety of applications, including use as components in films, coatings, fibers, impregnants, adhesives, printing inks, and binders, and use as modifiers, plasticizers, melt flow improvers, and leveling agents.
