Abstract
A polymer blend comprised of a polyketone and linear low density polyethylene (LLDPE). The blend is suitable for use with foodstuffs and liquid hydrocarbons. In a preferred form of the invention, the polyketone has an alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds.
Claims9
A polymer blend comprising a polyketone having an alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds and a linear low density polyethylene (LLDPE) wherein 1 to 50% by weight of the LLDPE is added to the polyketone.
A polymer-based container suitable for use with foodstuff wherein the polymer comprises a blend of a polyketone having an alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds and LLDPE having 1 to 50% by weight of the LLDPE added to the polyketone.
A polymer-based container suitable for use with liquid hydrocarbons wherein the polymer comprises a blend of a polyketone having an alternating structure of (a) units derived from carbon monoxide and (b) units derived from one or more olefinically unsaturated compounds and LLDPE having 1 to 50% by weight of the LLDPE added to the polyketone.
