Abstract

METODO DE OBTENER POLIMEROS CONTENIENDO AZUFRE. CONSISTE EN POLIMERIZAR ESTIRENO, A-METILESTIRENO, P-METILESTIRENO, VINILTOLUENO, ACRILONITRILO O METACRILATO DE METILO O MEZCLAS DE LOS MISMOS CON UNA VISCOSIDAD LIMITEDE 2 A 15 CC/G (MEDIDO EN DIMETILFORMAMIDA A 25JC) Y CON UN CONTENIDO EN AZUFRE DE UN 1,15 HASTA UN 3,95% EN PESO, PRESENTANDOSE UN 90% EN PESO DEL AZUFRE, INCORPORADO COMO COMPONENTE DE LOS GRUPOS DE C 1 A 18 TIOALQUILO TERMINALES. LA POLIMERIZACION SE REALIZA INCORPORANDO EMULSIONANTES ANIONICOS EN UN MARGEN DE TEMPERATURA DE 30 A 100JC Y EN PRESENCIA DE INICIADORES FORMADORES DE RADICALES. TIENE UTILIDAD PARA PREPARAR COMPOSICIONES DE MOLDEO.
