Abstract:
The purpose of this investigation is, therefore, a search for fossil resin substitutes. Natural resins, at present, are often treated to convert them to products that resemble the fossil resins to some extent. Artificial organic compounds often resemble resins and are used as substitutes for them. This paper is, therefore, entitled, "The Preparation of Treated and Artificial Resins and Their Use in Varnish Manufacture."
