  • Patent number: 9017800
    Abstract: Polymer compositions containing a polyoxymethylene polymer are disclosed that are receptive to paints and ink coatings. The polymer composition contains a polyoxymethylene polymer having a relatively high functional group content in combination with a coupling agent, a texturizing agent, and optionally a thermoplastic elastomer. The polymer composition can be molded into various articles at a mold temperature less than about 125° C., such as from about 60° C. to about 120° C. and then painted or printed with an ink composition. The polymer composition has been found to dramatically improve adhesion between the molded article and the ink or paint coating.

  • Patent number: 8840976
    Abstract: VOC or compressed gas containment devices, such as polymer fuel tanks, are made from a polyoxymethylene polymer composition. The polymer composition contains a polyoxymethylene polymer that is directly or indirectly chemically attached to an impact modifier. In one embodiment, for instance, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. In order to preserve the permeability of the polymer material when combined with the impact modifier, a polyoxymethylene polymer is used that contains a low level of low molecular weight constituents.

  • Publication number: 20140179841
    Abstract: An impact modified polyoxymethylene polymer composition is described containing a melt flow stabilizer. The polymer composition may contain a polyoxymethylene polymer containing functional groups, a thermoplastic elastomer and a coupling agent. A melt flow stabilizer is added to the composition in order to stabilize the melt volume flow rate of the composition after the components have been formulated. The melt flow stabilizer may comprise a pyridine derivative.

  • Patent number: 8481671
    Abstract: The present invention relates to a process for the preparation of oxymethylene polymers as well as oxymethylene polymers obtainable therefrom. The process includes polymerization of a monomer, which forms —CH2—O— units in the presence of an acetal of formaldehyde or a polyhydric alcohol and an initiator for cationic polymerization. The initiator may be a heteropoly acid or an acid salt thereof which is dissolved in an alkyl ester of a polybasic carboxylic acid.
