Abstract
"POLìMEROS LìQUIDOS PREPARADOS POR MODELAGEM (TLP'S) E EXTRUSãO REATIVA DESSES". A presente invenção é um processo para preparar polímeros de poliuretano extrudando um poliuretano líquido livremente fluente (TLP). Um TLP é preparado a partir de um poliisocianato e um poliol a baixa temperatura . Polímeros de poliuretano elastoméricos podem ser obtidos a partir do TLP por um processo de extrusão reativa. Os polímeros de poliuretano elastoméricos assim obtidos podem ser reprocessados como um fundido (processados por fusão) um número de vezes, e os polímeros podem ser conformados de várias formas úteis.
