Abstract
PROCEDIMIENTO PARA PREPARAR COMPOSICIONES MEJORADAS DE POLI(OXAZOLIDONA/URETANO). CONSISTE EN PREPARAR PREPOLIMEROS REACTIVOS CON ISOCIANATO QUE CONTIENEN AL MENOS UN GRUPO EPOXIDO TERMINAL CON UN GRUPO HIDROXI SECUNDARIO ASOCIADO, POR INJERTO DE UNA PARTE POLIMERICA DERIVADA DE LA POLIMERIZACION DE UN MONOMERO ETILENICAMENTE INSATURADO, CUANDO REACCIONAN CON ISOCIANATO; ESTA POLIMERIZACION SE REALIZA A TEMPERATURAS ENTRE 25 Y 135C.
