Abstract : The preparation of a Friedel-Crafts polymer from diphenoxydiphenylsilane and p-dichloroxylylene is described. Asbestos reinforced laminates bonded with the resin were examined for retention of mechanical properties after exposure to temperatures up to 300 C in air. The resistance to attack by acids and alkalis was also investigated. The thermal stability was found to be good in comparison with purely organic Friedel-Crafts resins, but the chemical resistance was poorer. A preliminary examination was made of a new type of Friedel-Crafts polymer (Mark 2) where the diphenoxydiphenylsilane was reacted with the dimethyl ether of p-xylylene glycol. (Author)
