FIELD: chemistry.
SUBSTANCE: invention relates to oligomeric urethane acrylates whose molecules contain a statistic average of at least two structural units of general formula I: R{-X-CH2-CH(-CH2-O-(O)-CR1=CH2)[-O-C(O)-NH-]}n, where n is a number from 1 to 6; R is an organic low-molecular or oligomeric radical, from monovalent to hexavalent; X is an oxygen atom or a -C(O)-O- group, a radical which is bonded to radical R through a carbon atom; and R1 is a hydrogen atom or a substituted or unsubstituted alkyl group containing 1-6 carbon atoms. The invention also describes a method of producing said compounds and use thereof as materials which are cured radically through activation with actinic radiation and/or thermal activation or for obtaining such materials.
EFFECT: obtaining novel oligomeric urethane acrylates which are activated with actinic radiation, have low viscosity and enable to obtain coatings with very good mechanical qualities, particularly high hardness, flexibility and deformability, considerable adhesion to different substrates, especially sheet metal, high resistance to the effect of chemical products and atmospheric corrosion, and also having remarkable effect from dull to satin gloss.
