Patent number: 7420009Abstract: Described is a low-emission adhesive, whose polymers are dissolved in a mixture of acetone and ethanol. The adhesive is characterized by very low emissions of solvents, with otherwise equally good properties compared to standard solvent-synthetic resin based adhesives. In particular with respect to viscosity and spreadability, surface tension, depth of penetration, wettability, simplicity and speed of processing, as well as adhesion, gluing strength and adhesive spectrum, the adhesive of the invention is equal to other adhesives based on solvents and thus superior to dispersion-adhesives that are based on aqueous solutions. Due to its low solvent emissions and absence of chlorinated solvents, the present adhesive is suitable for applications for which only dispersion-adhesives that are based on aqueous dispersions were reserved until now. This is true in particular for applications in enclosed spaces. The adhesive is very suitable for gluing of wooden floors in internal construction work.Type: GrantFiled: September 20, 2005Date of Patent: September 2, 2008Assignee: Stauf Klebstoffwerk GmbHInventors: Wolfgang Stauf, Frank Gahlman

Patent number: 6869985Abstract: Polymeric materials and products, including sheet flooring materials prepared from the polymeric materials, and processes for preparing the polymeric materials, are disclosed. The polymeric materials include a polylactic acid-based polymer in combination with plasticizer and a compatibilizer, and optionally include a filler. The polymeric material can include between about 30 to about 50 percent by weight polyvinyl chloride, polyethylene glycol, polyglycolide, ethylene vinyl acetate, polycarbonate, polycaprolactone, polyhydroxyalkanoates, or polyolefins modified with polar groups, for example, ionomers. The plasticizer is typically an epoxidized vegetable oil or esterified and epoxidized vegetable oil and is typically present in an amount of between about 10 and about 50% by weight. In some embodiments, the compatibilizer is a polyolefin modified with one or more polar functional groups, and is typically present in an amount of between about 5 and about 10% by weight.Type: GrantFiled: November 26, 2002Date of Patent: March 22, 2005Assignee: AWI Licensing CompanyInventors: Amar Kumar Mohanty, Lawrence T.

Patent number: 6780903Abstract: The invention relates to a new process for preparing polymer dispersions. According to the invention, a mixture is first formed of a polymer component, a plasticizer, dispersion auxiliaries and water, the mixture is then heated to approximately 20 to 100° C. in order to form a paste-like composition, and the paste-like composition is dispersed in water. The dispersion obtained according to the invention can be used for coating paper or board, as a primer, as a component in adhesives, paint or lacquer, and it is also suited for the manufacture of cast films and for use as a binder in materials based on cellulosic fibers.Type: GrantFiled: May 2, 2001Date of Patent: August 24, 2004Assignee: Valtion Teknillinen TutkimuskeskusInventors: Soili Peltonen, Maija Elina Heikkilä, Hannu Mikkonen, Jouni Hamara
