Title
(EN) Thermoplastic polyurethanes with crystalline chain ends
Abstract
(EN)

The present invention relates to novel thermoplastic polyurethane (TPU) compositions that have crystalline chain ends. The TPU compositions of the invention can provide improved resiliency, lower surface free energy, and/or reduced stickiness, while maintaining other desirable physical properties. The present invention also provides the described TPU compositions that are further grafted with vinyl alkoxysilane moieties allowing for crosslinked networks of the TPU compositions. The present invention also provides plasticizer-free, very soft TPU compositions without the processing difficulties often associated with such materials. The invention further provides means of reducing the surface tension of a TPU composition which can allow for improved blend compositions, and means of crosslinking the described TPU compositions.
