Abstract
The invention relates to a polymer blend composition containing (A) a linear alternating polyketone polymer on the basis of carbon monoxide and at least one ethylenically unsaturated hydrocarbon compound, (B) at least one polyamide and/or block copolyester amide, (C) optionally customary auxiliaries and additives such as stabilizers, pigments, fillers, plasticizers and impact modifiers, the polyamide and/or the block copolyester amide (B) having a carboxyl/amino end-groups ratio of more than 1.
Claims11
A polymer blend composition, the polymer blend composition comprising:
- a linear alternating polyketone based on carbon monoxide and at least one ethylenically unsaturated hydrocarbon compound, the linear alternating polyketone displaying recurring units of the following formula:
- --[CO(--CH.sub.2 --CH.sub.2)].sub.x --[CO--(G--)].sub.y (I)
- in which G is derived from an a-olefin monomer having at least three carbon atoms, at least two of the carbon atoms connected by an ethylenically unsaturated bond, x and y are whole numbers, and the ratio of y to x is not more than 0.5;
- and
- at least one polyamide having a numerical average molecular weight of above 5000, the polyamide having a carboxyl/amino end-groups ratio of more than 1, the mixture ratio of the polyamide to the polyketone polymer, relative to the polymer blend composition, being from 95 to 5 wt.-% to 5 to 95 wt.-% and the melting point of the polyamide not exceeding the melting point of the polyketone polymer.
