Title: Thermoplastic blend compositions as soft coupling agents

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.
