Lozhychevs'ka T. The hybrid binding agents on the modified polyester and epoxide oligomers base for polymeric composition materials

Introduction of amide group to the molecules of the unsaturated oligomers obtained by polycondensation of glycols with anhydrides of dicarbonic acids results in the improvement of copolymer properties on their base. It is noted, that in all cases the oligomer molecule contains the amide group. The copolymerisation processes obtained unsaturated polyester resins with metacrylic acid esters have been explored, the copolymerisation constants r1 and r2, Q-е factors, physical-mechanical and electro-physical properties of produced copolymers have been determined. The method of compatible hardening of the unsatureted polyester resins with the epoxide resins without use of initiator systems and hardening agents has been proposed. The investigated systems can be offered for the electroconductive composites of hot hardening obtaining for special application.
