STUDY LEADING TO THE DEVELOPMENT OF HIGH TEMPERATURE RESISTANT ADHESIVES
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)
