New class of reactive novolac: synthesis of bisphenol A-based novolac with methylol groups
We successfully prepared a new class of a reactive novolac ( 3 ) having a methylol moiety as a functional group derived from its precursor synthesized by the acid-catalyzed addition–condensation of a bisphenol A derivative and formaldehyde. Curing reaction between 3 and the low-molecular-weight phen...

| Zusammenfassung: | We successfully prepared a new class of a reactive novolac (
3
) having a methylol moiety as a functional group derived from its precursor synthesized by the acid-catalyzed addition–condensation of a bisphenol A derivative and formaldehyde. Curing reaction between
3
and the low-molecular-weight phenolic resin (
4
) afforded the curing product, which showed enhanced thermal stability compared with
4
or the conventional phenolic resin. Consequently,
3
can be applied as a curing agent to modify the thermal property of
