Patent number: 5883161Abstract: A moisture vapor barrier film composition can comprise a thermoplastic web comprising a thermoplastic polymer and a dispersed cyclodextrin composition having substituents that compatibilize the cyclodextrin in the film. The thermoplastic/cyclodextrin film obtains substantial barrier properties from the interaction between the substituted cyclodextrin in the film material with a water permeant. The substituents on the cyclodextrin molecule causes the cyclodextrin to be dispersible and stable in the film material resulting in an extrudable thermoplastic. Such materials can be used as a single layer film material, a multilayer film material which can be coated or uncoated and can be used in structural materials wherein the thermoplastic is of substantial thickness resulting in structural stiffness.Type: GrantFiled: September 16, 1997Date of Patent: March 16, 1999Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson

Patent number: 5880182Abstract: An admixture for decreasing the water demand of cementitious compositions such as concrete consists of(a) from 75-25% by weight of a water-reducing agent whose major component is a polycarboxylate; and(b) from 25-75% by weight of at least one saccharide component selected from hydrogenated saccharides and polyhydric alcohol adducts of saccharides.The saccaride component is preferably a hydrogenated polysaccharide with a molecular weight distribution as follows:(i) 70-30% by weight (on total weight of hydrogenated saccharides) have molecular weights in the range 180-300;(ii) 30-70% by weight have molecular weights of from 300 up to 4,000; and(iii) 30% by weight maximum have molecular weights of 4,000 and over.Type: GrantFiled: February 18, 1997Date of Patent: March 9, 1999Assignee: MBT Holding AGInventors: Yoshikazu Minomiya, Akira Ohta, Minoru Yaguchi

Patent number: 5837339Abstract: Carbonated beverages can have a substantially reduced concentration of water soluble materials derived from biaxially oriented thermoformed beverage containers. Such containers can comprise a permeant barrier and an active trap for water soluble materials that can be removed from the thermoplastic by extraction into the carbonated beverage. The improved container material comprises a blow molded thermoplastic polyester web comprising a compatible modified cyclodextrin material having pendent moieties or substituents that render the cyclodextrin material compatible with the container thermoplastic. The cyclodextrin material, after it is added to the polymer material, acts as a barrier and to trap extractable materials as they permeate through the thermoplastic polyester. The cyclodextrin molecule has a large center cavity having properties that increase the likelihood that organic molecules will be absorbed and trapped in the center pore.Type: GrantFiled: September 16, 1997Date of Patent: November 17, 1998Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson

Patent number: 5795928Abstract: A process is provided for preparing an acrylic copolymer latex having improved mechanical and shear stability comprising emulsion polymerizing at least one ethylenically unsaturated monomer having up to 23 carbons in the presence of, by weight based on the total monomer content, a) from about 0.05% to about 5.0% of a protective colloid with a molecular weight of less than 75,000, and b) from about 0.01% to about 1.5% of at least one water soluble free radical polymerization initiator. This latex provides coating manufacturers the flexibility of either eliminating surfactants altogether from coating or to use small amounts thereof.Type: GrantFiled: November 3, 1995Date of Patent: August 18, 1998Assignee: Hercules IncorporatedInventors: Bernardus J. W. Janssen, Gijsbert Kroon, Dirk Kruythoff, Willemina G. Salomons
