Abstract

A process for making a polyolefin composition having improved adhesive and/or coating compatibility involving: (a) providing a polyolefin; (b) providing from 0.01 to 10% by weight, based on the weight of the polyolefin, of a migratable amphiphile; (c) providing from 0.01 to 1000 ppm, based on the weight of the polyolefin, of a transition metal selected from the group consisting of titanium, tin, and mixtures thereof; and (d) combining (a)-(c) to form the polyolefin composition.
