STUDIES ON THE MIXED SYSTEM OF RUBBER AND ε-CAPROLACTAM

THE EFFECT OF ε-CAPROLACTAM ON RUBBERS (PART-1)

Abstract

The polymerization of ε-caprolactam in rubber was studied.
Usually ε-caprolactam was well known to be easy to polymerize in the presence of catalysts (water, acid, base, amine, etc.) at high temperatures about 200°C. The behaviors of various polymers in the temperature range of 180-240°C and the compatibility of these polymers with the melted ε-caprolactam at about 200°C were examined.
The possibility of grafting a polymer of ε-caprolactam on the carboxylic polybutadiene rubber was confirmed by chemical analysis.
Moreover, the effect of the addition of liquid carboxylated polybutadiene rubber on the polymerization of ε-caprolactam in the presence of sodium catalyst was studied.
