摘要
Abstract
Latex stage epoxidation of natural rubber with in-situ formed pefformic acid was studied under different feed composition and reaction temperatures. It was approved when reaction temperature was 30℃, the dry rubber content was 30 %, pH 2.0, the mole ratio of hydrogen peroxide, formic acid and NR was 1: 0.55: 1, the epoxidation could occur without side reaction. A comparative analysis of the epoxidecontent of ENR by IR, 1H-NMR and titrimetric technique had been made.关键词
