FIELD: chemistry.

SUBSTANCE: invention relates to adhesive and sealing substances, methods of their production and application. Disclosed are compositions containing a) a polymer selected from polyurethane or polyether, modified with at least one silane group (R¹)_a(X)_bSi-, where X is selected from R²O-, R²NH-, R²O-CO- and (R²)₂C=N-O-, R¹ and R² independently denote alkyl, cycloalkyl and/or aryl, a is equal to 0, 1 or 2, b is equal to 1, 2 or 3, and a + b = 3, and b) a mixture having shape of chains and/or cyclic siloxanes of general formula (I) and/or (II), in which (R) independently denote alkoxy, alkoxyalkoxy, alkyl, alkenyl, cycloalkyl and/or aryl, and some of (R) denote aminoalkyl-functional groups of formulae -C_oH_2o-NH₂, -C_oH_2o-NHR', -C_oH_2o-NRR', -C_oH_2o-NH-C_pH_2p-NH₂ or -C_oH_2o-NH-C_pH_2p-NH-C_qH_2q-NH₂, where R' is alkyl, cycloalkyl or aryl, and R assumes one of said values, or where residues R and R' bonded to a nitrogen atom, together with common nitrogen atom, form a heterocyclic ring having from five to seven members, where R' and R is assume one of said values, o independently denote integers from 1 to 6, p and q independently denote integers from 2 to 6, m is an integer from 2 to 30, n is an integer from 3 to 30, wherein one silicon atom compound of formula (I) and/or (II) is bonded to not more than one aminoalkyl-functional group, and wherein coefficient of molar ratio of Si and alkoxyl residues is at least 0.3.

EFFECT: compositions are ideal as adhesive substances and as sealing substances and are characterised by improved adhesion, especially on bases that are hard to glue to each other.
