Patent
CA 2416379
The present invention discloses self foamable and cross-linkable Organoclay/Novolak nanocomposites, foams and process thereof. The nanocomposites and foams disclosed herein comprise a layered silicate component and a novolak resin component. Nanocomposites compositions may also further comprise a surfactant and a curing agent. The layered silicate is intercalated by reaction with an intermediate having two functional groups, one of the group reacting with the layered silicate, the other participating to the condensation reaction with phenolic compounds. Foams generated from Organoclay/Novolak nanocomposites disclosed herein show improved mechanical properties. Furthermore, the process of producing such foams is greatly simplified by the use of water as the foam blowing agent. Water may originate from the condensation reaction of monomers (a phenol and an aldehyde) or from the volatile content of a novolak polymer.
