Abstract

Processo per la polimerizzazione in sospensione acquosa di monomeri acrilici in presenza di un sospendente polimerico, omopolimero e copolimero di un composto di formula: (FORMULA I) in cui: R1 è H e CH3; R2 e R3, uguali e diversi, sono H e alchili C1-C8, eventualmente ramificati quando possibile; H è un metallo alcalino e alcalino - terroso e ammonio ed A è H, O oppure CH3, caratterizzato dal fatto che la fase acquosa di polimerizzazione è costituita in tutto o in parte dalle acque madri ottenute dopo la separazione del polimero acrilico, in modo da avere una sospensione del polimerizzabile contenente almeno lo 0,01%in peso e fino a circa l'1% di detto sospendente e almeno da 0,05% e 5% in peso dei suddetti altri prodotti ottenuti in polimerizzazione.
