Bakelite is produced by the Nordiske Kabel and Traadfabrikker A. S. Fabrikvej at Copenhagen. Other brands made in Denmark are Nokait, Helomit, and Etronit. There are 14 manufacturers of finished products, making electrical equipment principally. POLAND Production of synthetic resins in Poland in 1936 totaled 660,000 pounds, entirely of the tar-acid type. 16. RAW MATERIALS FOR ALKYD RESINS The alkyd resins are made chiefly from phthalic anhydride and glycerin. Phthalic anhydride in turn is made from naphthalene. Polybasic acids such as maleic, succinic, etc., may also be used with glycerin to form alkyd resins. Naphthalene, phthalic anhydride, maleic and other polybasic acids, and glycerin are discussed in the order named. NAPHTHALENE
