Process for the preparation of epoxidized polybutadienes

摘要

Epoxidized polybutadienes with an average molecular weight of 500 to 100,000 and a certain content of epoxide oxygen were prepared from the corresponding polybutadienes with use of perpropionic acid in a benzene solution. The solution can also be employed in unpurified form with maximum contents of 1.5 weight percent hydrogen peroxide 1.5 weight percent of water, and about 800 ppm of mineral acid.
