Abstract
Pueden fabricarse poli(éter-uretanos) a partir de éteres cíclicos y de isocianatos orgánicos usando, como catalizadores, compuestos metálicos seleccionados. Los polímeros, utiles como elastomeros plásticos, fibras spandex o gomas de uretano, pueden fabricarse haciendo reaccionar diisocianatos que contienen grupos funcionales con un tetrahidrofurano, especialmente el tetrahidrofurano mismo. La invencion también describe un proceso mejorado para la polimerizacion cationica de unéter cíclico usando un isocianato orgánico.
