Popis:	henolic and amino resins on the basis of α,β-unsaturated aldehydes were synthesized in bulk or solution. Catalysts were HCl, H 3 PO 4 , or formic acid, and in some cases NaOH. The course of the reactions is influenced by experimental conditions: the type of monomers, their molar ratio, the type and quantity of the catalyst, the reaction time and temperature, and the reaction medium. The overall rate constants for the beginning of the reactions were between 10 -3 L/mol s for the high reactive mixtures and 10 -7 L/mol s for the less reactive mixtures.
