Abstract
Inventia se refera la un procedeu pentru obtinerea unei rasini melaminoformaldehidice eterificate, utilizabila în industria cauciucului, în care se efectueaza reactia, într-o singura treapta, între melamina, formaldehida, metanol, în raport de 1/7...7,5/22...30, de preferinta, 1/7...3/23...27, în cataliza heterogena pe cationat de tip stirenic, puternic acid, luat în proportie de 80...250 g/mol, de preferinta, 150...200 g/mol melamina reactanta, utilizîndu-se o solutie apoasa de formaldehida înconcentratie de 37...77%, de preferinta 40...50%, si o solutie metanolica de formaldehida cu maximum 10% apa.
