Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania bezformaldehydowej żywicy melaminowej, który polega na tym, że w temperaturze 55 - 65°C miesza się 10 - 15 części wagowych melaminy i 70 - 85 części wagowych glioksalu, po czym wprowadza się wodny roztwór NaOH lub KOH, o stężeniu 35 - 55% wagowych, do uzyskania pH 4 - 5, a następnie wprowadza się 5 - 12 części wagowych alkoholu lub poliolu i miesza się przez 0,5 – 2 godzin.
