Abstract: Hydroxyalkylamines can, in addition to imparting antistatic properties, significantly improve the color, i.e., the whiteness, of polyolefin resins produced with chromium-based catalysts and metallocene catalysts. Additionally, such compounds can impart improved whiteness at a loading significantly lower than that required to impart antistatic properties. Surprisingly, the discovered improvement in whiteness is not, however, observed in resins produced using other types of catalysts.

Abstract: Disclosed is a method for stabilizing a crude oxy-methylene copolymer having thermally unstable terminal groups, which comprises subjecting a crude oxymethylene copolymer to heat treatment in the presence of at least one quaternary ammonium compound represented by the following formula (1): [R1R2R3R4N+]nX−n  (1) wherein each of R1, R2, R3 and R4 independently represents an unsubstituted or substituted alkyl group, an aryl group, an aralkyl group which is an unsubstituted or substituted alkyl group substituted with at least one aryl group, or an alkylaryl group which is an aryl group substituted with at least one unsubstituted or substituted alkyl group; n is an integer of from 1 to 3; and X is a hydroxyl group or an acid residue. In this method, even by the addition of a very small amount of the quaternary ammonium compound, the decomposition rate of the unstable terminal groups can be remarkably increased, thereby facilitating the stabilization of the crude copolymer. Therefore, by this method, it has become possible to easily produce an excellent oxymethylene copolymer within a short period of time, which has substantially no unstable terminal groups and, therefore, has excellent thermal stability and color tone.

Abstract: There is provided a rubber composition whose run-flat durability is improved and in which precipitation of sulfur and a vulcanization accelerator on the rubber surface before vulcanization is prevented. Sulfur in an amount of 2 to 8 parts by weight and two or more vulcanization accelerators in a total amount of at least 5 parts by weight based on 100 parts by weight of a rubber component are used, at least one of the accelerators being a sulfen amide accelerator.

Abstract: The color stability of thermoplastic polymers comprising structural units derived from at least one 1,3-dihydroxybenzene and at least one organodicarboxylic acid is enhanced by combination with at least one photobleachable 4-aminocinnamic compound such as 4-dimethylaminocinnamaldehyde. The latter absorbs radiation in the range between about 360 nanometers and about 390 nanometers, balancing the radiation absorbed by hydroxybenzophenone moieties formed in the polymer.

Abstract: Perfluoroelastomer compositions comprising perfluoroelastomers having copolymerized units of tetrafluoroethylene, a perfluoro(vinyl ether), and a nitrile-containing cure site monomer are cured with certain nitrogen-containing nucleophilic compounds. The nucleophilic compounds also act as dual curatives in perfluoroelastomer compositions which incorporate other curing agents.
