Abstract:
CHEMICAL MODIFICATIONS WERE ATTEMPTED ON POLY2,6-XYLENOLS AND CONDENSATION TRIAZINE TYPE POLYMERS WHICH HAD BEEN FOUND TO BE SUITABLE BASE MATERIAL FOR HIGH TEMPERATURE ADHESIVES FOR SAINLESS STEEL. Poly-2,6xylenol was prepared. High molecular weight polyxylenols had goodADHESION 2000-3000 psi t room temperature, but lost srength to 10 of the original after heating at 550 F. for 30 min. The low molecular weight material may flow better and therefore impart better wetting. Several low molecular weight polyxylenols were prepared. 2-Methyl-6allyl-4-bromophenol was prepared and a polymer was prepared from it by the Price method of oxidative couphing. Nitration of 2,4,6-triphenyls-triazine yields 2,4-di-m-nitrophenyl-6phenyl-s-triazine. Reduction of this derivative gives the diamino compound. Author
