Abstract


EPOXIDATION OF HYDROXYL-TERMINATED LIQUID NATURAL RUBBER

BY 3-CHLOROPERBENZOIC ACID

The epoxidation reaction of hydroxyl-terminated liquid natural rubber (~ 4510) by 3-chloroperbenzoic acid in dichloromethane at 250C was studied. The FTIR, 13C- NMR, 1H-NMR and DEPT spectra show that epoxidized liquid natural rubber (~4560¸4880) has been formed.
