Compositions for forming molded articles, particularly, shells for automotive applications are made up of melt blends of an aliphatic thermoplastic urethane elastomer and one or more polyolefin-based modifiers. These compositions may be blended to form a powder, pellets, microspheres or minibeads which may then be cast to form air bag door and instrument panel cover skins which may meet automotive deployment and weathering requirements.

Thermoplastic polyurethane copolymer molding compositions

Compositions for forming molded articles, particularly, shells for automotive applications are made up of melt blends of aliphatic thermoplastic urethane elastomer and an olefin-containing block copolymer crosslinked to a gel content of from 5 to 95%. These compositions may be blended to form a powder, pellets, microspheres or minibeads which may then be cast to form air bag door and instrument panel cover skins which may meet automotive deployment and weathering requirements.

The present invention relates to low viscosity polymer polyols and to a process for the preparation of these low viscosity polymer polyols. These polymer polyols comprise the free-radical polymerization product of (A) a base polyol, (B) a pre-formed stabilizer, and (C) at least one ethylenically unsaturated monomer, in the presence of (D) at least one free-radical polymerization initiator, and (E) at least one polymer control agent. The total amount of polymer control agent present in the polymer polyols of the present invention ranges from greater than about 5.0% up to about 20% by weight, based on 100% by weight of the polymer polyol.
