Abstract
A polyoxymethylene composition of good thermal stability, consisting of (A) formaldehyde or trioxan homopolymer (or copolymer obtained from formaldehyde or trioxan and comonomer (e.g. carbon monoxide ketene, ethylene oxide, isobutylene, styrene etc)) modified and at the same time stabilised by treating reactive terminal groups, (B) polyamide (e.g. 6-nylon, 66-nylon, 6,10-nylon, 7-nylon, etc), and (C) 4,4'-thiobis (3-methyl-6-tert-butylphenol). The amount of (B + C) is preferably 0.01-5 wt.% based upon A. The wt. ratio of C to B is pref. about 1/1 to 1/10. The polyoxymethylene composition is excellent in thermal stability and does not colour, and mouldings can be made from the composition by injection, extrusion etc.
