POLYKETONE WITH IMPROVED COLOR, AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2018/026047

Kind Code:

A1

Abstract:

The present invention relates to a polyketone composition which is prepared by blending and extruding: a linear alternating polyketone consisting of carbon monoxide and at least one olefinically unsaturated hydrocarbon; and a maleic anhydride, wherein a base resin of the produced polyketone has a yellowness index of 15 or less and, more specifically, to a polyketone composition having a maleic anhydride content of 100 ppm to 15,000 ppm with respect to the total weight of the polyketone composition. Also, provided is a polyketone molded part produced using the polyketone composition. The polyketone composition prepared according to the present invention can improve discoloration stability by improving the yellowness index (YI) of the base resin to 15 or less. Thus, the polyketone composition allows for the reduction of a master batch processing cost for a color concentrate, and the cost of a pigment such as titanium dioxide (TiO2), and the like.
