Abstract
A thermoplastic elastomer polyurethane is made having improved properties such as flexural modulus, flexural strength, and improved melt processability. An unaged polyurethane containing free isocyanate groups is made in situ in a high shear blending apparatus. The unaged polyurethane is typically transferred to another high shear blending apparatus and blended with either an unmodified polyolefin and/or a carbonyl modified polyolefin along with optional but desirable fibers to produce a thermoplastic elastomer polyurethane composition.
