Abstract
There is provided a process for improving the color of anhydride-grafted polymers. The process includes the steps of admixing in an extruder a polyolefin, a free radical initiator, and an anhydride-providing monomer at a temperature above the melting point of the polyolefin, adding an effective amount of an oxo-boron compound to the admixture; and extruding the resultant anhydride-grafted polymer into a shaped article.
