Effect of formulation and technological parameters on properties of polyurethane glues based on regenerated polyol produced by chemical destruction of an elastic polyurethane under the action of a mixture of oligooxypropylenetriol (M ≈ 5000) and N,N,N′,N′-tetrahydroxy propylene ethylenediamine was studied. Introduction of an additional amount of polar urethane and urea groups into the polyurethane glue from the regenerated polyol results in that the glued joint has a high adhesion to the surface of substrates of varied nature. This circumstance makes the formulation competitive with industrial brands of glues intended for construction purposes.
