Patent number: 8501308Abstract: Thermoplastic polymer compositions, films, continues, closures, laminates can comprise a modified vinyl polymer said modified polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, locked into the polymer structure, can absorb impurities, permeants, or other undesirable volatile materials. The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.Type: GrantFiled: April 13, 2006Date of Patent: August 6, 2013Assignee: Cellresin Technologies, LLCInventors: Willard E.

Patent number: 8114148Abstract: According to an aspect of the present invention, at least one ionic therapeutic agent is delivered from an implantable or insertable medical device that comprises an ion-conductive polymeric region that is disposed on a metallic region. The metallic region is in electrical contact with a dissimilar metallic region, such that a galvanic current is generated by the dissimilar metals when the device is implanted or inserted into a patient. Delivery of the ionic therapeutic agent from the ion-conductive polymeric region may be, for example, either accelerated or retarded by the galvanic current.Type: GrantFiled: June 23, 2009Date of Patent: February 14, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Liliana Atanasoska, Jan Weber, Paul Grosso, Robert W.

Patent number: 6210792Abstract: The invention relates to a composition comprising a thermoplastic polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The polymer, the fiber or both can be modified to increase compatibility. The wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process. The linear extrudate or pellet can have a cross-section of any arbitrary shape, or can be a regular geometric. The pellet can have a cross-section shape having a volume of at least about 12 mm3. Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg. The invention also relates to an environmentally sensitive recycle of waste streams. The polymer and wood fiber composite contains an intentional recycle of a waste stream comprising polymer flakes or particles or wood fiber.Type: GrantFiled: November 12, 1998Date of Patent: April 3, 2001Assignee: Andersen CorporationInventors: Kasyap V.

Patent number: 5981067Abstract: The invention relates to a composite pellet comprising a thermoplastic polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The fiber can be modified to increase compatibility. The polymer and wood fiber composite may contain an intentional recycle of a waste stream which can comprise adhesive, paint, preservative, or other chemical waste stream common in the wood-window or door manufacturing process. The initial mixing step before extrusion of the composite material insures substantial mixing and melt contact between molten polymer and wood fiber. The extruded pellet comprises a consistent proportion of polymer, wood fiber and water.Type: GrantFiled: October 14, 1997Date of Patent: November 9, 1999Assignee: Andersen CorporationInventors: Kasyap V.
