    摘要: This invention is directed to crosslinkable systems comprising a crosslinker B and an organic polymer P having aromatic moieties with increased electron density in comparison with benzene at unsubstituted carbon atoms in the said aromatic moiety, wherein the crosslinkers B are aromatic compounds having least two diazonium groups of formula - ⊕ N≡N, to a process for the preparation of these crosslinkable systems, and to a method of use thereof in the preparation of adhesives and coating films comprising these crosslinkable systems.

    摘要: The invention is directed to modified resins M based on oligomeric or polymeric phenolic materials K, where diazonium compounds B carrying at least one further functional group which is hydrophilic or hydrophobic, or alters the surface tension or of the resins so modified, are coupled to the said phenolic materials K via an azo coupling reaction. The oligomeric or polymeric phenolic materials K are selected from the group consisting of novolaks N, resoles R, and polymers P particularly including lignin L and tannin T, having aromatic moieties with increased electron density in comparison with benzene at unsubstituted carbon atoms in the said aromatic moiety. The diazonium group-containing modifiers B are aromatic compounds having a diazonium group of formula - ⊕ N≡N, and at least one further functional group which is hydrophilic or hydrophobic, or otherwise influences the cohesion and adhesion properties of the resins so modified, such as perfluoroalkyl groups or oligo- and poly-siloxane groups.
