Abstract

SE PRESENTAN METODOS MEJORADOS PARA LA FORMACION DE ELASTOMEROS DE URETANO Y LOS PREPOLIMEROS DE URETANO CORRESPONDIENTES EN DONDE SE MEZCLAN Y SE HACEN REACCIONAR SIMULTANEAMENTE UN DIISOCIANATO Y UN DIOL DE BAJO PESO MOLECULAR PARA FORMAR UN SEGMENTO DURO AL CUAL SE LE HACE REACCIONAR DESPUES CON UN DIOL DE CADENA LARGA PARA FORMAR EL ELASTOMERO. LOS DIISOCIANATOS ALIFATICOS SON PARTICULARMENTE ADECUADOS PARA LA FABRICACION DE LENTES DE CONTACTO A PARTIR DE LOS PREPOLIMEROS DE URETANO DE ESTA INVENCION.
