Abstract
A phenol-aldehyde resin composition consisting essentially of the polymerization product of an alkali organic extract of peanut hulls and pecan piths polymerized with an aldehyde. The peanut hull and pecan pith alkali organic extract are polymerized with an aldehyde and used to formulate resins suitable for use in polywood adhesives, in molding compounds, in wood bonding agents and in cellulosic material impregnating agents.
