Compositions of Thermoplastic polyurethane (TPU), polybutadiene and TPU based polidieno

摘要

A composition comprising: a) a Thermoplastic polyurethane (TPU) comprising less than 25% by weight of a Diene derived Units; (b) and polybutadiene or polyisoprene; and (c) a TPU based polidieno what comprises at least30% by weight of a Diene derived units. Usually and preferably, TPU (a) does not contain any derived Unit of a Diene.These compositions can be cured to form Thermoplastic vulcanizates.Both nocuradas cured compositions and are very suitable to promote adhesion between polar Materials (For example, polyester, polycarbonate, and polylactic acid) and non-polar and Manufacturing, among other things, films, Fibers, films and Layers of Union, tubes, Adhesives, dispe Rsiones, protective clothing, Footwear, Coatings, laminates and foams.
