Abstract
Se producen poliuretanos/ureas segmentados utiles en la produccion de espandex por prolongacion de cadena de un prepolimero acabado en isocianato en presencia de un solvente. El prepolimero acabado en isocianato se forma por reaccion de un exceso estequiometrico de un isocianato con un componente reactivo con isocianato que incluye mas de un 50 por ciento en equivalentes de un polioxialquilendiol de alto peso molecular que tiene un nivel de insaturacion no mayor de aproximadamente 0,015 meq/g y hasta aproximadamente un 50 por ciento en equivalentes de un politetrametilen eter glicol.
