Abstract

Los artículos médicos formados a partir de una resina a base de poliuretano que incluyen un oligómero modificador proporcionan propiedades mejoradas. Un oligómero modificador incorporado en una estructura, como cadena lateral, o ambos de la resina a base de poliuretano formada por un diisocianato, un poliglicol y un extensor de cadena de diol tiene al menos uno, preferiblemente dos, restos de alcohol (C-OH) y un resto funcional. Los oligómeros modificadores de ejemplo son: un perfluoropoliéter que contiene diol incorporado en la estructura, un polisiloxano monofuncional (por ejemplo, polidimetilsiloxano terminado en monodialalcohol) incorporado como cadena lateral, y combinaciones de estos. Los artículos médicos de este documento son autolubricantes y/o antiincrustantes.
