Abstract
PROCEDIMIENTO DE OBTENCION DE POLIMERIZADOS DE CLORURO DE VINILO. EL MONOMERO O LA MEZCLA DE MONOMEROS SE POLIMERIZAN EN DISPERSION ACUOSA CON CATALIZADORES FORMADORES DE RADICALES Y, OPCIONALMENTE, CON ESTABILIZADORES DE LA SUSPENSION Y EMULGENTES. PARA EVITAR LA FORMACION DE CAPAS EN LAS PAREDES DEL REACTOR DE POLIMERIZACION, SE RECUBREN CON UN COMPUESTO DE FORMULA (I), EN QUE R1 Y R2 SON RADICALES HIDROCARBURO SATURADOS; R3 Y R4 SON RADICALES HIDROCARBURO SATURADOS GRUPO HIDROXI O AMINA SECUNDARIA; R5, R6 Y R7 SON HIDROGENO, HIDROCARBURO SATURADO, CON O SIN OXIGENO, PUDIENDO SER R5 Y R6 UN PRODUCTO AROMATICO ISOCICLICO O HETEROCICLICO, Y X UN ANION UNIVALENTE. DE APLICACION EN LA OBTENCION DE POLIMERIZADOS DE CLORURO DE VINILO QUE CONTENGAN, AL MENOS, 50 POR 100 EN PESO DE UNIDADES POLIMERIZADAS DE CLORURO DE VINILO. *FORMULA*
