Zusammenfassung:	Both the oligomer and the method are used in the application of the manufacture of electrical equipment and that of lacquers and paints. The prepared product reacts at lower temperatures with a minimum release of gaseous products during its trimeric structurization. The oligomer represents a post-reaction product of an ordinary thermoplastic novolak phenolaldehyde oligomer, obtained in a medium of organic solvent at temperature 78 degrees C. Insulation compounds can be prepared from it by solidification at 120-140 degrees C for 30-60 minutes.
