    摘要： 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.

    摘要： There is disclosed a novel aluminum alloy bearing which exhibits a more excellent fatigue resistance than conventional bearings even under such conditions of use as at a high temperature and under a high load. The aluminum alloy bearing has an aluminum bearing alloy layer containing, by weight, 1 to 10% Zn, 0.1 to 5% Cu, 0.05 to 3% Mg, 0.1 to 2% Mn, 0.1 to 5% Pb, 0.1 to 2% V, and 0.03 to 0.5% in total of Ti--B, and further may optionally contain not more than 8% Si, 0.05 to 0.5% Sr, and Ni, Co and Cr. The alloy may be bonded to a steel metal back sheet, and a surface layer may be formed on the surface of the bearing. By use of the composition of the alloy of the invention, the fatigue resistance of the aluminum alloy bearings has been improved, and such an improved bearing can fully achieve a bearing performance even under severe conditions of use as at high temperature and under a high load.
