The synthesis of bromo derivatives cardanolic novolac resins (BCNR) using infrared, thermogravimetric analysis, differential scanning calorimetry, gel permeation chromatography, nuclear magnetic resonance 1 H and 13 C methods was studied. The mechanism of thermal degradation of BCNR is proposed. It is shown, that particleboards manufactured using PU-(BCNR) as an adhesive are materials with enhanced flame retardant properties, meeting the requirements of P7 class to EN 312 (especially durable moistureresistant particleboards) and the requirements of the emission class Super E0. The bromine in the structure of the cardanolcontaining polyurethane binder allows achieving both high physical and mechanical characteristics of the particleboards and resistance to flame.

To study the influence of technological factors upon physico mechanical characteristics of chip boards containing a cardanol containing polyurethane adhesive as a binder, a five factor experiment was car ried out twice in accordance with the Box-Wilson central composite design. The calculated optimal condi tions for the chipboard pressing process have been proven by experimental data.
