Patents with Abstracts

8,188,169 
Polyoxymethylene compositions and articles made from these
 
Moraczewski and Pollino of DuPont, Delaware, developed polyoxymethylene compositions that include 90 to 99.9 wt% of at least one polyacetal polymer and 0.1 to 10 wt % of at least one polysaccharide substantially free of acidic material selected from the group consisting of amylopectin from maize and soluble starch. (RDC 6/7/2012)

8,178,627 
Oxymethylene copolymer composition for stretching material, stretching material, structures, and process for producing the same
 
Okamura of Mitsubishi, Japan, developed an oxymethylene copolymer material for a stretched material having a high strength and a high elastic modulus.  This material consists of an oxymethylene copolymer; and a crosslinkable compound to be blended with 0.001 to .05 phr oxymethylene copolymer. The present invention also relates to a stretched material obtained by using the oxymethylene copolymer composition. Further, the present invention relates to a structure obtained by the secondary processing of the above stretched material, and a structure obtained by using the above oxymethylene copolymer composition in a bonding layer of the structure. The present invention also relates to a method of producing a structure, the method including: using the oxymethylene copolymer composition in a bonding layer of the structure; and removing a polyalkylene glycol component with water or a solvent. (RDC 5/29/2012)

8,138,247 
Polyoxymethylene compositions and articles made from these
 
Shinohara and Shibuya  of DuPont, Delaware, developed a polyoxymethylene material consisting of (a) 20 to 80 wt% polyacetal homopolymer, copolymer, or mixtures of these; (b) 5 to 40 wt% glass fiber; (c) 0.1 to 2 wt% polymeric thermal stabilizer selected from the group consisting of polyacrylamide, polymethacrylamide, and mixtures of these; (d) 0.02 to 2 wt% allantoin; and 0.1 to 5 wt% of an ethylene copolymer of the formula E/X/Y; wherein Y includes a glycidyl group (RDC 5/16/2012)
