ABSTRACT:
The present invention relates to a process for the preparation of epoxidized synthetic cis-1,4-polyisoprene. The process involves reacting the synthetic cis-1,4-polyisoprene in a C.sub.5 -C.sub.7 aliphatic hydrocarbon with tertiary butyl hydroperoxide in the presence of a molybdenum catalyst at a reaction temperature ranging from about 20.degree. C. to about 100.degree. C. The molybdenum catalyst is prepared by reacting together under a N.sub.2 atmosphere molybdenum pentachloride with a carboxylic acid of the formula:
