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.

Thermoplastic blend compositions as soft coupling agents

Disclosed herein are p-urea phenyl derivatives of the formula: wherein Rand Rare independently selected hydrocarbyl groups. These derivatives are useful as haze reducing agents in propylene polymers and copolymers.
