The interaction or compatibilization of a polyolefin with a filler is promoted by the presence of reactive functionality in the polymer, e.g. carboxyl groups in ethylene-acrylic acid copolymers and maleic anhydride- and acrylic acid-grafted polyethylene and polypropylene, capable of chemical reaction or hydrogen bonding with the functionality, generally hydroxyl, on the surface of the filler. Interaction also results from graft copolymerization of an unsaturated trialkoxysilane, e.g. methacrylatopropyl- or vinyl- trialkoxysilane, or alkoxy titanate with the polyolefin, prior to, or concurrent with, compounding with the filler, or from pretreatment of the filler with the silane or titanate, so that the pendent unsaturation reacts with the radical sites generated on the polymer during compounding.
