摘要：
PROBLEM TO BE SOLVED: To obtain a macromonomer which has no unpleasant odor nor discoloration, can be stored with no side reaction and has reactivity at its terminal, or a stable, liquid epoxidized natural rubber which is useful as a raw ingredient for various materials such as an adhesive or a tacky agent and has a narrow molecular weight distribution and to provide a method of efficiently manufacturing the same.
SOLUTION: The liquid epoxidized natural rubber is manufactured by epoxidizing a natural rubber so that a degree of epoxidization is 1-75%, preferably after deproteinizing it so that its nitrogen content is 0.1 wt. % or below, and depolymerizing it using a radical initiator and an aldehyde.
