Abstract
The present invention is a flame retardant polyketone polymer composition which comprises: (a) a bicyclic phosphorus flame retardant compound, such as one containing one or more pentaerythritol phosphate alcohol moieties, as exemplified by bis(pentaerythritol phosphate alcohol) carbonate; (b) an intumescent flame retardant compound containing nitrogen and phosphorus, such as melamine phosphate; and (c), optionally, a monophosphate ester compound to enhance the compatibility of the composition in the polymer substrate, such as a liquid aryl-group containing phosphate ester compound or melamine phosphate, and the monophosphate ester compound is triphenyl phosphate.
Claims12
A flame retardant polyketone composition which comprises:
- (1) a linear, alternating polyketone polymer formed by the polymerization of carbon monoxide and at least one olefin;
- and a (2) a flame retardant which comprises (a) a bicyclic, pentaerythritol phosphate alcohol-derived phosphorus flame retardant compound;
- (b) an intumescent flame retardant compound containing nitrogen and phosphorus;
- and (c), optionally, an aryl group-containing monophosphate ester compound to enhance the processability of the composition in the polymer substrate.
