摘要： The present disclosure relates to a molding composition and to molded products made from the composition. In accordance with the present disclosure, the polymer composition contains a polyoxymethylene copolymer having a relatively low amount of comonomer units. The polyoxymethylene polymer is combined with at least one reinforcing fiber and a coupling agent. The above polymer produces a composition have a relatively high heat deflection temperature, while also having excellent mechanical properties.

摘要： A polyoxymethylene polymer is disclosed that contains long-chain alkyl end groups. The polyoxymethylene polymer may be formed by using a Bis-alkylformal as a chain transfer agent during production of the polymer. In one embodiment, the Bis-alkylformal is dissolved in a monomer, such as trioxane, during production of the polymer. In one embodiment, a branching agent may also be present with one or more monomers for producing a branched polyoxymethylene polymer. In this manner, greater amounts of alkyl end groups can be incorporated into the polymer. The resulting polymer has excellent flow characteristics. The polymer may be used to form various molded articles with excellent tribological properties.
摘要翻译： 公开了含有长链烷基端基的聚甲醛聚合物。 聚甲醛聚合物可以通过在聚合物的制备过程中使用双烷基甲酰胺作为链转移剂形成。 在一个实施方案中，在制备聚合物期间将双烷基甲酰胺溶解在单体如三恶烷中。 在一个实施方案中，支化剂也可以与一种或多种用于制备支化聚甲醛聚合物的单体一起存在。 以这种方式，可以将更多量的烷基端基引入聚合物中。 所得聚合物具有优异的流动特性。 聚合物可用于形成具有优异的摩擦学性质的各种模制品。
