摘要： A polyacetal resin composition prepared by adding about 0.01 to 10 parts by weight of a glyoxydiureide compound to 100 parts by weight of a polyacetal resin. The glyoxydiureide compounds usable herein include glyoxydiureide itself and derivatives thereof (such as metal salts thereof). About 0.01 to 10 parts by weight of a basic nitrogen compound may be further added thereto. The nitrogen compounds usable herein include melamine, melamine resins, and polyamide resins. In addition, an antioxidant may be added to the composition. The compositions serve to improve the stability, particularly the thermal stability, of the polyacetal resin, and prevents the evolution of formaldehyde.

摘要： A cyclic polyoxymethylene with a number-average molecular weight of 500 to 5,000 is produced by treating an alkali-decomposable linear polyoxymethylene homopolymer in an organic liquid medium containing a cationically active catalyst in solid form at 10 to 150 DEG C for 1 to 500 min to effect cyclization. The reaction mixture obtained by the cyclization is treated with an alkaline medium to remove unreacted linear polyoxymethylene homopolymer by hydrolysis, thus isolating cyclic polyoxymethylene. The product has a narrow molecular weight distribution and is useful as a resin modifier.
