The study of reaction between isoamyl alcohol and epoxidized liquid nature rubber

Abstract

Epoxidized liquid natural rubber with 25 % mol epoxide content was prepared by reacting phenyihydrazone terminated liquid natural rubber with 3-chloroperbenzoic acid. The reaction between isoamyl alcohol and epoxidized liquid natural rubber catalysed by cerium ammonium nitrate was achieved in dichloromcthane solution at 30 °c. Structure of polymers was determined by 'H-NMR and ‘^C-NMR, thermal stability of polymers also was investigated by thermal gravimetric analysis (TGA). The results showed that the epoxide ring opening epoxidized units lead to the formation of hydroxyl and isoamyl groups and thermal stability of product is lower than epoxidized liquid natural rubber.
