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.

Abstract: Hard, infusible, discrete beads of crosslinked copolymer are prepared by free-radical catalyzed polymerization of a monomer mixture in aqueous dispersion wherein a minor amount of a modifier, specifically an organic compound containing acetylenic or allylic unsaturation having the ability to moderate the rate of polymerization, is incorporated in the monomer mixture. Ion exchange resins having improved mechanical strength are obtained by attaching functional groups to the copolymer.

Abstract: The method of modifying latex paints for maintenance paint applications, primarily on iron or steel industrial and transportation structures, in order to provide both short term and long term corrosion resistance, and the resulting composition, are described. Two types of corrosion encountered in painting ferrous surfaces with latex paint are: (1) flash rusting which occurs as a result of contact with the water from the latex and results in rust bleed-through at the time the paint is drying, and (2) rust bleeding, which may occur over a period of months or years. It has now been found that the benefits of both water soluble corrosion inhibitors, for preventing flash rusting, and water insoluble corrosion inhibitors, for minimizing blistering and rust bleeding, are achieved by utilizing a soluble complex of a polyvalent metal, a volatile complexing agent, and a corrosion inhibiting anion. This complex may be represented by the formulaM(Z).sub.

Abstract: Described herein is a pigment paste for use in an aqueous paint comprising a film-forming latex polymer, a pigment and a dispersant copolymer. Also described is the dispersant copolymer which serves the function of dispersing the pigment in the preparation of the paste and maintaining the dispersion in the paste and paint made therefrom. The dispersant copolymer is such that its complex salt formed with Zn++ and ammonia is water-soluble at a pH of 9.6. The dispersant is a copolymer of an .alpha.,.beta.-unsaturated monovinylidene carboxylic acid and at least one other ethylenically unsaturated monomer. The dispersant is particularly adapted to preparing paste for difficult-to-formulate paints such as paints with reactive pigments and paints requiring high levels of dispersant.

Abstract: A method for removing cumene vapor from a cumene-containing vapor stream comprises passing the vapor stream through a bed of a substantially dry hydrophobic, macroreticular, water-insoluble, crosslinked polymer containing from 20% to 100% by weight of the polymer, of divinylbenzene or a copolymer of divinylbenzene, the balance being ethylvinylbenzene or styrene or mixtures thereof but not more than 50% of either ethylvinylbenzene or styrene, until the capacity of the polymer or copolymer to remove cumene is substantially exhausted. Thereafter, the cumene is desorbed from the mass or bed of the polymer or copolymer by passing steam through said mass or bed. Without drying, the mass or bed is then ready for reuse.

These compounds possess biological activity and in particular are useful as systemic protectant/eradicant fungicidal agents for controlling plant diseases caused by fungi and as plant growth regulators. The metal complex salts of these compounds are particularly useful in their ability to reduce undesirable plant growth regulatory activity and phytotoxicity while retaining their ability for controlling plant diseases caused by fungi.

Abstract: An effective amount of a vinylbenzyltrialkylammonium 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 vinylbenzyltrialkylammonium salt lessens or avoids the usual problems associated with the conventional anionic, nonionic or cationic emulsifiers employed in aqueous polymerizations. 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.
