Characterization of resins prepared by polycondensation of egyptian bagasse pith and bisphenol A. Part I. Physicochemical properties of the moulded shapes

Optimum conditions have been established for the synthesis of linear, soluble, and easily mouldable condensation products from Egyptian bagasse pith using bisphenol A as the condensation agent. Thin layer chromatographic technique was used for characterizing the products. The obtained condensate resins were treated with phenol formaldehyde, anthracene formaldehyde, and naphthalene formaldehyde to get different types of moulded products, which were found to be mechanically harder and chemically more stable than those of a phenol formaldehyde resin of novolac type.
