| 3968306 | Plastic articles having improved surface characteristics A plastic article having improved surface characteristics comprises a plastic body having adhered thereon a cross-linked film of a composition comprising (A) 10 to 90 parts by weight of a cross-linking unsaturated compound having a molecular weight of M a... | 07/06/1976 |
| 3963685 | Alcohol soluble hydrophilic polymer via aqueous polymerization Hydrophilic, water insoluble, organic solvent soluble polymers of hydroxyalkyl methacrylate or acrylate of high purity are prepared in water using hydroxyalkyl methacrylate or acrylate monomer having not over 0.035 weight percent of alkylene glycol dimeth... | 06/15/1976 |
| 3963798 | Thixotropic, radiation curable compositions A reactive metal oxide or metal hydroxide, such as ZnO, MgO, HgO or Ba(OH)2 and acrylic or methacrylic acid are added to a liquid, hydrophobic, essentially solvent-free coating vehicle capable of being cured by high-energy radiation. The result... | 06/15/1976 |
| 3960824 | Mercaptan initiated polymerization process carried out in the presence of oxygen Low molecular weight polymers of ethylenically unsaturated monomers are prepared by a bulk polymerization process using organic mercaptans as the polymerization catalysts and carried out in the presence of oxygen. These low molecular weight polymers find ... | 06/01/1976 |
| 3957711 | Dispersion polymerization process using hydroxyalkyl acrylate as protective colloids Aqueous dispersions of synthetic polymers have been made by polymerizing ethylenically unsaturated monomers in water in the presence of a protective colloid which is a polymer of a hydroxyalkyl acrylate or methacrylate. Such aqueous dispersions are useful... | 05/18/1976 |
| 3940351 | Polymerization of carboxylic acid monomers and alkyl acrylate esters in chlorofluoroethane Improved copolymers of unsaturated copolymerizable carboxylic acid monomers and one or more alkyl acrylate esters containing 10 to 30 carbon atoms which serve as efficient thickeners of aqueous solutions, even in the presence of substantial amounts of ino... | 02/24/1976 |
