摘要： A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer and at least one tribological modifier. The tribological modifier may comprise an ultra-high molecular weight silicone having a kinematic viscosity of greater than 100,000 mm2 s−1. When tested against itself, the composition of the present disclosure exhibits an extremely low dynamic coefficient of friction and produces no discernible noise over a very broad temperature range, such as from −20° C. to 60° C.

摘要： A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer, reinforcing fibers, and at least one tribological modifier. The tribological modifier, in one embodiment, can comprise a graft copolymer. The use of a graft copolymer has been found to unexpectedly and dramatically improve noise generation when tested against various substrates, especially glass substrates.

摘要： The synthesis of nanoparticles based on hyperbranched-linear-hyperbranched ABA triblock copolymers with hyperbranched polyglycerol (hbPG) as A-block and linear poly(oxymethylene) as B-block is described. The acid-degradable nanoparticles were formed in a facile process, combining a solvent evaporation process with the miniemulsion technique resulting in particles with a diameter in the range of 190 to 250 nm and a standard deviation of ˜30% determined with DLS and SEM. The nanoparticles were placed on a silicon wafer and sintered leading to films with a thickness in the μm-range investigated via SEM. The surface properties of these films were investigated via static contact angle measurements at the liquid/vapor interface. The contact angle decreases from 67° for the polymer with two hydroxyl groups to 29° for the polymer with 16 hydroxyl groups, confirming the influence of the polymer structure and size of the hbPG block on the surface properties.

摘要： A method of preparing a polyacetal comprising polymerization of a mixture comprising a plurality of at least one bis-acetal monomer in the presence of an acid catalyst that promotes the metathesis of the acetal units. The bis-acetal can be formed from an acid catalyzed exchange between a mono-acetal monomer with a diol. The formation of the bis-acetal and the polyacetal can be carried out simultaneously. The diol can be isolated from a biorenewable source and the ultimate polyacetal is a degradable or biodegradable polymer.

摘要： A composition contains (a) 1 to 40 weight percent of poly(phenylene ether) particles having a mean particle size of 1 to 40 micrometers; and (b) 60 to 99 weight percent of a polyoxymethylene; wherein polystyrene is absent from the poly(phenylene ether) particles; wherein the composition comprises less than 0.1 volume percent, based on the total volume of the composition, of particulate metals, metalloids, oxides thereof, and combinations thereof, wherein the metals and metalloids are selected from iron, copper, aluminum, magnesium, lead, zinc, tin, chromium, nickel, tungsten, silicon, gold, silver, platinum, and alloys thereof. The poly(phenylene ether) particles reduce the density and increase the char yield of the polyoxymethylene. When the composition is prepared at a temperature below the glass transition temperature of the poly(phenylene ether), increased flexural strength can also be obtained. The composition is useful as a molding composition for a variety of articles.
