Compatibilized polyketone polymer blend

Abstract

A blend of polyketone and polycarbonate polymers is presented. The polymer blend is produced by blending polyketone polymer, polycarbonate polymer, and a reactive graft compatibilizer. The a reactive graft compatibilizer compatibilizes the blend.

We claim as our invention: 
     
       1. A compatibilized polymer blend comprising a linear alternating polymer of carbon monoxide and one or more ethylenically unsaturated hydrocarbons, a polycarbonate polymer, and a minor amount of a compatibilizer comprising about 60% wt polycarbonate and about 40% wt nylon 6. 
     
     
       2. The blend of claim 1 wherein the ratio of polyketone to polycarbonate is between about 3:1 and 1:3 (based upon total weight of said blend). 
     
     
       3. The blend of claim 1 comprising about 40 wt % of polyketone, about 40 wt % of polycarbonate, and about 20 wt % reactive graft compatibilizer. 
     
     
       4. The blend of claim 1 wherein said polycarbonate polymer is selected from the group consisting of ##STR4## wherein Ar is selected from the group consisting of phenylene and alkyl, aryl, alkoxy, aryloxy, halogen and nitro-substituted phenylene; Z is a divalent hydrocarbon radical containing 1-15 carbon atoms, m is an integer of 0 or 1, and p is an integer of at least 2. 
     
     
       5. The blend of claim 1 wherein said polycarbonate polymer is a polycarbonate of bisphenol A. 
     
     
       6. The blend of claim 1 wherein said reactive graft compatibilizer comprsies nylon 6 and a polycarbonate of bisphenol A. 
     
     
       7. An article of manufacture made from the blend of claim 1.
