Abstract

La presente invencion es un poliuretano termoplástico rígido que tiene una Tg de por lo menos 50 degree C que tiene una concentracion suficiente de unidades termoplástico rígido puede ser procesado por fusion. La presente invencion también es un poliuretano termoplástico con un modulo de flexion de por lo menos 690,000 kPa, y que tiene una concentracion suficiente de unidades de un diol aromático para disminuir la temperatura a la cual el poliuretano termoplástico puede ser procesado por fusion. Las composiciones de la presente invencion muestran mejorada de procesamiento con pérdida insubstancial de propiedades físicas.
