More Information
Summary:A polymer composition stabilised against degradation during melt processing which comprises (a) a major amount of a polymer of carbon monoxide and at least one 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.
