ABSTRACT:
Alkali metal aldehyde lignin-cellulose silicate polymers are reacted chemically with an epihalohydrin compound to produce a polyepoxy silicate resin; the polyepoxy silicate resin may be cured by a catalyst, e.g., an amine or Lewis acid, to produce a cured epoxy resin, solid or cellular solid product which may be used as an adhesive, as construction sheets, etc.
