Abstract
Procedimiento de preparación en masa en dos fases, de polímeros y de copolímeros a base de cloruro de vinilo con poca proporción en producto grueso, según el cual se realiza en una primera fase una operación de polimerización o copolimerización bajo agitación de turbulencia elevada, en una composición monómera a base de cloruro de vinilo, hasta que se obtenga un grado de conversión de la composición monómera del 5 al 15%, eventualmente se añade al medio reaccionar una cantidad complementaria de una composición monómera a base de cloruro de vinilo idéntica a o diferente de la empleada durante la primera fase, y después se realiza durante la segunda fase, en el medio reaccionar así formado, una operación de polimerización o de copolimerización final a una velocidad de agitación lenta.
