The synthetic resin film for agriculture is obtained by using (a) an ester of sorbitan with a higher fatty acid mainly containing 24 to 34 carbon atoms (montanic acid wax), an ester of glycerin with montanic acid wax and/or alkylene oxide adducts thereto and/or an ester of polyoxyalkylene with montanic acid wax as an anti-clouding agent, and (b) a fluorine-containing surfactant as an anti-fogging agent, kneading them with a film-forming resin such as vinyl chloride resin, polyethylene, ethylene/vinyl acetate copolymer, and forming it into a film.Type: GrantFiled: September 14, 1999Date of Patent: May 7, 2002Assignee: Clariant Finance (BVI) LimitedInventors: Takuya Hoga, Hiroshi Ohsawa, Masaki Nakamura

Patent number: 6372882Abstract: The present invention is a method of producing substantially dry water insoluble polymers from poly alkyl esters of vinylic monomers for use in a method for the clarification of red mud-containing liquors generated in the Bayer process for the recovery of alumina from bauxite ore. The polymers can be either homopolymers, copolymers or terpolymers. Preferably, the dried emulsion polymers are high molecular weight polymers of poly(methyl acrylate), poly(methyl acrylate/acrylic acid), poly(vinyl acetate/acrylic acid/methyl acrylate), poly(t-butyl methacrylate/acrylic acid/methyl acrylate) and poly(t-butyl acrylate/acrylic acid/methyl acrylate).Type: GrantFiled: April 3, 2000Date of Patent: April 16, 2002Assignee: Nalco Chemical CompanyInventors: Everett C. Phillips, Ronald J. Allain

Patent number: 6323268Abstract: A composition for rendering surfaces water repellent is formed by combining water or a solvent; a methylhydrogensiloxane polymer or copolymer; an alkoxysilane having the formula RaSi(OR′)4-a in which R represents an alkyl group containing 1-10 carbon atoms, an alkenyl group containing 2-8 carbon atoms, an aryl group, or an haloalkyl group, a has a value of 1 or 2, and R′ represents an alkyl group containing 1-6 carbon atoms; and a silicone resin. The composition can also contain other components such as a volatile methyl siloxane, a cationic oil-in-water emulsion of an aminofunctional polydimethylsiloxane, a surfactant, a catalyst, a beading agent, an organic wax, a preservative, an antifoam, a mildewcide, an UV absorber/UV light stabilizer, or a freeze-thaw additive.Type: GrantFiled: June 27, 2000Date of Patent: November 27, 2001Assignee: Dow Corning CorporationInventors: Paul David Fisher, Feifei Lin, Lori Ann Stark-Kasley

Patent number: 6300398Abstract: The subject invention is directed to polymer compositions which comprise a homogeneous ethylene/&agr;-olefin interpolymer, a wax and a nucleating agent, wherein the nucleating agent is provided in an effective amount such that the percent elongation at break of the polymer composition is at least about fifty percent greater than the percent elongation at break of a comparative composition which lacks the nucleating agent. The polymer compositions of the invention will find utility in applications r equiring high elongation at break, while maintaining a high onset of crystallization temperature, such as in the high-speed coating of fabrics, carpet backing, floor tile and sheeting, and adhesives.Type: GrantFiled: April 14, 1998Date of Patent: October 9, 2001Assignee: The Dow Chemical CompanyInventors: Gary Lee Jialanella, Thomas J. McKeand, Jr., Kalyan Sehanobish
