ABSTRACT:
A polymer composition stabilised against degradation during melt processing which comprises (a) major amount of a linear alternating copolymer of carbon monoxide, ethylene, and a C.sub.3 -C.sub.6 normal olefin (b) a minor effective amount of a first stabiliser comprising an aluminium trialkoxide, an aluminium phenoxide or an aluminium containing hydrolysis product of such compounds and (c) a minor effective amount of a second stabiliser comprising an organic epoxy containing compound. The aluminium trialkoxide is suitably aluminium isopropoxide and the organic epoxy containing compound is, for example, epoxidised soybean oil.
