Abstract

Processo per produrre copolimeri modacrilici comprendenti acrilonitrile, un comonomero alogenato e un comonomero contenente gruppi idrofili mediante polimerizzazione in continuo dei monomeri in sospensione acquosa ed in presenza di un catalizzatore, in cui la polimerizzazione viene condotta in un reattore tubolare provvisto di troppo - pieno (overflow) ed avente un rapporto lunghezza/diametro superiore a 1,8; il catalizzatore, l'acrilonitrile e il comonomero contenente i gruppi idrofili vengono alimentati nella zona inferiore del reattore e il comonomero alogenato nella zona superiore di detto reattore; il catalizzatore è del tipo ad alta velocità di decomposizione tale da decomporsi per almeno il 70% in peso, nelle condizioni di polimerizzazione, prima di incontrare la zona di alimentazione del comonomero alogenato.
