Abstract
In 1935 G. Walter published an article on “The Condensation of Urea and Formaldehyde” at the Faraday Society Symposium on “Phenomena of Polymerisation and Condensation.” There he postulated new chemical formulae for the two crystalline condensation products, i. e. Meth A and Meth B. But these have been rejected by almost all resin chemists, besides, his other works seem to have little been cited in the literatures. To clarify the state of affairs the present author introduced and discussed Walter's articles on “Constitution of Synthetic Resins.” : Part I, II (1931) and IX (1934) with the article of the “Symposium.”
