Abstract

A process for lowering the stiffness of filled thermoplastic polymer formulations is disclosed wherein the process comprises including in said formulation a low modulus coupling agent wherein said coupling agent comprises a blend of at least two functionalized polyolefins. Also disclosed is a process for producing soft coupling agents comprising blending at least two functionalized polyolefins in pre-determined ratios, whereby chemical and physical properties of the coupling agents can be controlled.

Claims (5)

1. A process for lowering the stiffness of filled thermoplastic polymer formulations comprising including in said formulation from about 10 weight percent to about 15 weight percent of a low modulus coupling agent wherein said coupling agent comprises a blend of a maleic anhydride functionalized polypropylene, a maleated ethylene propylene diene, and a maleated homo polypropylene-g-MA.

2. The process of claim 1 wherein the low modulus coupling agent has a flexural modulus ranging from 100 MPa to 1500 MPa.

3. The process of claim 1 wherein the filled thermoplastic polymer is a filled polyolefin.

4. The process of claim 1 wherein the filler of the filled thermoplastic polymer is selected from the group consisting of calcium carbonate, talc, calcined kaolin, mica, feldspar, dolomite, wollastonite, silica, glass, calcium silicate, china clay, wood flour, barite, calcium sulfate, titanium dioxide, asbestos, rock flour, heavy spar, barium sulfate, metal oxides and hydroxides, carbon black, graphite, and combinations thereof.

5. The process of claim 4 wherein the filler is talc.
