THE EFFECT OF ε-CAPROLACTAM ON RUBBERS

(PART II) THE EFFECT OF ε-CAPROLACTAM ON SBR

Abstract

The graft polymerization of ε-caprolactam on SBR was studied. It was found that ε-caprolactam could be grafted on SBR even in the absence of catalyst, but the reaction would be accelerated by adding the catalystic agents, and that triethanolamine and phosphoric acid were the most effective in catalytic action among the several agents tested in this work.
With an increase in the amount of catalyst and ε-caprolactam, the amount of ε-caprolactam grafted on the rubber increased. The grafted rubber had better physical properties.
