Abstract

Invenţia se referă la o compoziţie antiincrustantă pentru acoperirea suprafeţelor reactoarelor de polimerizare pentru monomeri de tip lichid. Această compoziţie se obţine prin condensarea unui naftol cu un produs de reticulare aldehidic. Pentru obţinerea produsului de condensare, este utilizat un hidrosulfit care conţine hidrosulfit şi/sau radicali bisulfitici şi/sau bisulfit. Produsul de condensare, astfel obţinut, în absenţa oxigenului, este sub forma unui lichid cu o culoare transparentă, clară.
