A B S T R A C T POLYKETONE POLYMER COMPOSITION Polymer composition comprising a non-miscible blend of: (1) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, (2) a mineral filler, and (3) a polyether esteramide polymer, and optionally, (4) an acidic polymer incorporating moieties of an .alpha.-olefin, an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and optionally a non-acidic, low molecular weight polymerizable monomer, the acidic polymer optionally having a portion of the carboxylic acid groups neutralized with non-alkali metal, show good dimensional stability while maintaining good strength and impact resistance |
