Abstract

Чрез метода се предотвратява образуването на полимерен налеп в полимеризационния съд по време на полимеризация на голям брой мономери, включващи двойна връзка в молекулата си. Той се прилага ефективно, независимо от вида на материала, от който са изработени стените на полимеризационния съд. По метода вътрешната повърхност на стените на полимеризационния съд предварително се покрива с разтвор на водна основа, съдържащ компонент (а) от водоразтворимо анионно багрило и компонент (в), представляващ поне едно съединение, подбрано от групата, състояща се от водонеразтворимо катионно багрило и водонеразтворимо азотсъдържащо органично съединение, като рн на разтвора е до 7. След полагане на покритието следва изсушаване.17 претенции
