Beschreibung
Zusammenfassung:	A bridging composition is described and claimed for cross-linking phenolic resols or forming novolac resins. The composition contains at least partially sulphonated cyclic phenolic oligomers, optionally combined with at least partially sulphonated linear phenolic oligomers and/or sulphonated phenol. Unlike conventional catalysts used for cross-linking resols or forming novolac resins, said composition is chemically built into the structure of the final products and provides them with novel or modified properties while accelerating said reactions.
