Abstract

LOS COMPUESTOS DE POLIISOCIANATO QUE LLEVAN GRUPOS URETANO Y GRUPOS UREDIONAS SON SOLIDOS POR DEBAJO DE 40 POR ENCIMA DE 125 C. ESTOS COMPUESTOS LLEVAN UN CONTENIDO EN GRUPOS URETANO DE AL MENOS UN 1 % EN PESO. ESTOS GRUPOS URETANO SE OBTIENEN HACIENDO REACCIONAR DIMERDIOLES CON GRUPOS ISOCIANATO. SE DESCRIBE TAMBIEN UN PROCEDIMIENTO PARA LA OBTENCION DE TALES COMPUESTOS HACIENDO REACCIONAR POLIISOCIANATOS QUE LLEVAN GRUPOS URETDIONAS CON UNA FUNCIONALIDAD MEDIA DE NCO DE AL MENOS 2, UTILIZANDO A VECES OTROS DIISOCIANATOS, CON DIMERDIOLES, A VECES OTROS DIOLES Y/O A VECES COMPUESTOS MONOFUNCIONALES EN RELACION CON GRUPOS ISOCIANATO. SE UTILIZAN ESTOS NUEVOS COMPUESTOS DE POLIADICION COMO COMPONENTES DE PARTIDA PARA LA OBTENCION DE PLASTICOS DE POLIURETANO, ESPECIALMENTE COMO COMPONENTES DE RETICULANTES EN PINTURAS EN POLVO DE POLIURETANO DE DOS COMPONENTES RETICULABLES POR EL CALOR.
