FIELD: resin industry and organometallic synthesis.
SUBSTANCE: organometallic composition for solidifying polyisocyanate materials, which may be used for binding lignocellulose, contains complex of at least one metal ortho-ether having formula M(ROAcAc)x(OR')y, where M represents titanium, zirconium, or hafnium; ROAcAc represents moiety of acetoacetic acid ester with alcohol ROH wherein R is optionally cyclic, branched, or linear alkyl, alkenyl, aryl, or alkylaryl group having 1 to 30 carbon atoms or mixture thereof; OR' represents alcohol R'OH residue wherein R' is optionally cyclic, branched, or linear alkyl, alkenyl, aryl, or alkylaryl group having 7 to 30 carbon atoms or mixture thereof; each of x and y ranges between 1 and 3 and x+y=4. Mixture to be solidified contains organic isocyanate compound or mixture of organic isocyanate compounds and above-indicated organometallic composition. Lignocellulose product, containing lignocellulose material and polyisocyanate composition including above-indicated organometallic composition, is prepared by bringing lignocellulose material into contact with above polyisocyanate composition to allow lignocellulose material to be bound.
EFFECT: improved process characteristics of organometallic composition.
