Abstract
Blends of polyketone polymers with polyolefin polymers are described which are compatibilized by a reactive blend of a polyamide polymer and a maleated polyolefin polymer. The compatibilization is attained without chemical linkage between the compatibilizer and the polyketone polymer. Such compatibilized blends offer good mechanical properties and the ability to melt bond to both neat polyketone polymers and neat polyolefin polymers.

A composition comprising a non-miscible blend of a polyketone polymer, a polyolefin polymer and, as a minor component, a compatibilizer, itself comprised of a reactive blend of an amine terminated polyamide polymer and a maleated polyolefin polymer.
A composition comprising a non-miscible blend of a polyketone polymer, a polyolefin polymer and, as a minor component, a compatibilizer, itself comprised of a reactive blend of an amine terminated polyamide polymer and a maleated polyolefin polymer, and
- where the polyketone polymer is comprised of an alternating structure of (a) units prepared from carbon monoxide and (b) units prepared from one or more olefinically unsaturated compounds, and
- where the polyketone polymer is present in a quantity from about 15 to 85 weight percent, based on the total compositions, and
- where the polyolefin polymer is present in a quantity from about 15 to 85 weight percent, based on the total composition.
