Abstract

Invenţia se referă la un procedeu pentru protecţia reactoarelor de polimerizare a monomerilor în suspensie apoasă şi/sau în emulsie, prin depunerea pe pereţii interiori ai acestora a unui produs antiincrustant, obţinut prin reticularea alcoolului polivinilic cu produsul format prin reacţia sării de sodiu a acidului hidroximetansulfinic cu naftol.
