Progress in Elaboration of Chemical and Abrasion Resistant Materials

The latest published achievements in the research and developments of non-isocyanate polyurethanes on the base of five-membered cyclic carbonates and amines are briefly presented. Preparations of hybrid epoxy-amine hydroxyurethane-grafted polymers with a controlled number of cross-links are described. Examples of the use of hydroxyurethanes of different nature for modification of the oligomeric compositions are also given.

“…The experiment used rubber PBNR with viscosity (Pa*s.): 0.4; 0.6; 0.8; 1.0; 1.2; 1.4; 1.6; 1.8; 2.0; 2.2. The regression analysis of the obtained results allowed deduction of mathematical models adequately describing the correlation of durability of the samples against compression and bending: σ com = 46.377η(l − 0.36η) + 60.731 (1) σ b = 33.564η(l − 4.2η) + 10.553 (2) where σ com is the durability of PBNR -RubCon samples against compression, MPa; σ b is that against bending; η is the rubber viscosity, Pa*s.…”

Development of manufacture of linear diene oligomers belonging to a liquid rubbers class with viscous liquids consistence allowed to create a new class of conglomerate polymer composite materials -rubber concrete (RubCon®). Rubber concrete is the advanced constructional material created for last years. It is polymer concrete with a unique set of physical-mechanical, chemical and technological properties which allow to obtain highly effective building structures and products on its basis.
