FIELD: chemistry.
SUBSTANCE: epoxidation process for butadiene-styrene rubber involves the treatment of a butadiene-styrene copolymer solution with a monobasic carboxylic acid containing from 1 to 3 carbon atoms and hydrogen peroxide with a monobasic carboxylic acid/hydrogen peroxide molar ratio of greater than 1, forming an in situ epoxidizing agent.
EFFECT: invention avoids gelling, makes it possible to simplify the method.
