Abstract
Procedimiento mejorado para la preparación de compuestos de moldeo de poliéster, comprendiendo (A) una resina de poliéster insaturada teniendo (1) una proporción de grupos hidroxilo a grupos carboxilo, entre alrededor de 5,7 y 0,8 y (2) un número de ácido de por lo menos 14 y, (B) un peso molecular medio entre alrededor de 800 y 5.000; (C) un monómero alifáticamente insaturado y (1) un catalizador de polimerización de radical libre, caracterizado porque se introduce dentro de dicha mezcla de reacción de compuestos de resina de poliéster, antes de curar (B) (1) un poliisocianato orgánico en una cantidad suficiente para reaccionar con por lo menos 30%, pero no más de 105% de los grupos hidroxilo presentes y (B) (2) un óxido e hidróxido metálico seleccionado del grupo consistente en óxidos e hidróxidos de calcio y magnesio en una cantidad suficiente para reaccionar con por lo menos 30%, pero no mas de 75% de los grupos carboxilo presentes, para producir por ello una elevación controlable en viscosidad de dichos compuesto moldeador y un índice de viscosidad mejorado.
