THE CURE OF DICYCLOPENTADIENE DIOXIDE
二氧化双环戊二烯的固化

Dicyclopentadiene dioxide was hardly cured by amines or acid anhydrides alone, but can be well cured by acid anhydrides mixed with alcohols. The curing process using different amounts of maleic anhydride and glycerol were studied, and the influence on gel time and temperature-deformation curve were determined. Although dicyclopenta-diene dioxide is a diepoxide compound, the cured resin formed a more rigid molecular chain, therefore a plastic which shows no glass transition point before the decomposition temperature (ca. 300°)may be obtained under optimum amount of curing agent and proper curing conditions.
