Abstract: There are disclosed polymerizable alkyl poly(oxyalkylene) esters of an acrylate oligomer and copolymers thereof, especially stable, aqueous dispersions of water-insoluble emulsion copolymers of (1) about 10-70% by weight of methacrylic or acrylic acid, (2) about 0.5-25% by weight of an alkyl poly(oxyalkylene) ester of an acrylate oligomer, and (3) at least 25% by weight, to a total of 100%, of a C.sub.1 -C.sub.4 alkyl (meth)acrylate, and optionally, included in the total monomer mixture, a small amount of (4) about 0.5-1% by weight, of a polyethylenically unsaturated monomer. The copolymers, when neutralized and solubilized by addition of an alkali, are high efficiency thickeners for aqueous systems and have improved tolerance to ionic or electrolyte content. Typical systems that can be thickened are paint latices, cosmetic preparations, food preparations, ionic detergents, dye pastes for textiles, pharmaceuticals, and oil well drilling muds.

Abstract: There are disclosed polymer concrete compositions of essentially anhydrous character comprising (1) an inert inorganic particulate material, such as sand, crushed stone or rock, and mixtures thereof, mixed with (2) a monomer blend of (a) dicyclopentenyloxyalkyl methacrylate or acrylate and (b) hydroxyalkyl methacrylate to form a paste or slurry suitable upon addition thereto of (3) a polymerization catalyst of (a) an organic peroxide and an aromatic amine accelerator, or (b) a polyvalent metal salt or complex and an organic hydroperoxide, or (c) mixtures of (a) and 0.0005% to 2% by weight, based on total amount of monomers, of a polyvalent metal salt or complex, or (d) mixtures of (a) and (b), to be used to form or to patch previously formed or laid, concrete floors and road pavements or as a coating for a variety of substrates such as metal and plastic sheet.

Abstract: Nonionic and anionic water-soluble addition copolymers of acrylamide and N-substituted acrylamides are useful as flow modifiers in and as adsorbates from aqueous systems, particularly multiphase systems. The copolymers have a weight average molecular weight greater than 30,000 and are useful for many purposes including as thickening agents or rheology modifiers for water based systems, block improvement additives in water based coating formulations, and transfer aids in water based ink or roll coater formulations.
