摘要：
Polyurethane derivatives of petroleum asphaltites that can be used as adhesive materials were obtained by reacting the products of condensation of resin-asphaltene components with formaldehyde-formalites and diisocyanates. In contrast to industrial polyurethane adhesives, they provide a stronger bond for metal surfaces (St3), are more resistant to variable temperatures from +60 to − 60°C, and to g radiation with a dose of up to 3.7 × 106 Gy.
