Abstract
Uso de agentes tensioactivos en la polimerizacion en suspension de monomeros fluorados para preparar fluoropolímeros que contienen hidrogeno, teniendo dichos agentes tensioactivos la formula general: Rf-[L-(OCHR1-CHR2)m-OZ)]i, en donde: i es igual a 1 o 2; m es un numero entero comprendido entre 4 y 60; L puede seleccionarse entre. -(CFY-CO-O)pR'- y -(CFY-CO-NH)pR'-, en donde p es un numero entero igual a 0 o a 1; Y = F, CF3; R' = a radical alquílico de C1-C5, lineal o ramificado cuando sea posible; R1, R2 pueden ser ambos H o el primero H y el ultimo CH3, Z puede ser H, radical alquilo de C1-C3, lineal o ramificado cuando sea posible; o (CH2)nOH siendo n un numero entero de 1 a 6; Rf es un radical perfluoroalquílico o un radical perfluoropoliéter, que tiene un peso molecular medio en numero comprendido entre 250 y 1500.
