heal.abstract	The adhesion characteristics of modified polycyanurates based on the principle of semi-interpenetrating polymer networks (semi-IPNs) have been studied. It has been shown that the formation of a polycyanurate network in the presence of linear polyurethane (LPU) leads to increasing adhesion strength to aluminum and titanium. The peculiarities of polycyanurate network (PCN) formation in the presence of different amounts of LPU are discussed. It has been found that chemical incorporation of LPU into PCN occurs during network formation owing to chemical interaction of urethane groups with cyanate groups of growing PCN. At LPU content in the initial composition up to around 20 wt% only a hybrid network is formed. The maximal values of adhesive strength to aluminum and titanium are achieved at LPU content of 20-25%, corresponding to formation of a hybrid network. The further increase of LPU content leads to the presence of non-incorporated LPU (semi-IPN formation) in the adhesive layer and to reduction of the adhesive strength.	en
