Patent number: 4774308Abstract: An actinically curable composition containing (1) an oligomer having a molecular weight within the range of from about 200 to about 3000 and which is end capped with reactive functional groups to provide sites for free radical polymerization by actinic radiation and (2) as a reactive diluent, an N-vinyl-2-oxazolidinone in which the number 4 and 5 carbon atoms each have two constituents which are all independently selected from hydrogen and alkyl radicals having from 1 to 4 carbon atoms.Type: GrantFiled: July 7, 1986Date of Patent: September 27, 1988Assignee: The Dow Chemical CompanyInventors: John G. Green, David G. Hunt

Patent number: 4772463Abstract: CDP-choline derivatives with macromolecules containing carboxy groups, such as polyacrylates, polymethacrylates, polyglutamates, polyaspartates and polymaleates, or copolymers of acrylic acid and methacrylic acid with methyl acrylate, methyl methacrylate or acrylamide.The polymeric derivatives of the invention gradually release CDP-choline, due to the action of enzymes present in the organism, thus exerting also a protective effect on the CDP-choline molecule.Type: GrantFiled: September 30, 1986Date of Patent: September 20, 1988Inventors: Vincenzo Zappia, Mario De Rosa

Patent number: 4769427Abstract: Finely divided, gel-like crosslinked polymers are prepared by a continuous method in which a monomer mixture which contains, per 100 parts by weight of acrylic acid or methacrylic acid, from 50 to 100 mol % of which in each case are neutralized, acrylamide, methacrylamide or N-vinylpyrrolidone, from 0 to 30 parts by weight of other water-soluble monoethylenically unsaturated monomers and from 0 to 20 parts by weight of water-insoluble monoethylenically unsaturated monomers is copolymerized with from 0.01 to 5 parts by weight of a crosslinking agent, in 20-65% strength by weight aqueous solution in the presence of an initiator at from 45.degree. to 95.degree.
