Abstract
La presente invencion se refiere a un poliuretano fundido obtenible mediante un proceso que comprende el hacer reaccionar (a) un poliol de polidieno que tiene un peso molecular promedio en numero entre 500 y 500,000 con (b) un isocianato o prepolímero de isocianato que tiene dos o más grupos isocianato por molécula, y luego se cura el producto de reaccion con un agente de curacion aromático el cual tiene menor polaridad como se determina mediante un parámetro de solubilidad de menos de 10.5. Preferentemente, el poliol de polidieno es un diol de polibutadieno hidrogenado. La presente invencion se refiere además a los artículos que contienen los poliuretanos fundidos.
