Abstract RU 2778682 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to the application of a compound of the general formula (I)

in which B means an aromatic hydrocarbon group, which is a divalent group, which is obtained by removing isocyanate groups from an aromatic diisocyanate selected from a group consisting of 1,3-diisocyanatobenzene, 1,4-diisocyanatobenzene, 2,4-diisocyanatotoluene, 2,6-diisocyanatotoluene, 2,4’-diphenylmethane diisocyanate, 4,4’-diphenylmethane diisocyanate and 1,5-diisocyanatonaphthalene, and each R1 independently represents a branched or linear aliphatic alkylene group having 1-15 carbon atoms, to increase the adhesion stress of the cured fixing mass.

EFFECT: expansion of the range of methacrylate compounds.
