Abstract
A functionalized polyketone and a method to make this functionalized polyketone is provided, the method including the steps of: providing a polyketone; contacting the polyketone with a functional group containing monomer, the functional group containing monomer having a double bond between two carbons, at a temperature between about 180° C. and 275° C., for a time period effective for at least 10% by weight of the resultant grafted polymer to be grafted monomer units; and recovering the grafted polyketone.

A method to produce a grafted polyketone, the method comprising the steps of:
- providing a polyketone;
- contacting the polyketone with a functional group containing monomer, the functional group containing monomer having a double bond between two carbons, at a temperature between about 180° C. and 275° C., for a time period effective for at least 10% by weight of the resultant grafted polymer to be grafted monomer units;
- and
- recovering the grafted polyketone.
