对引发剂B,在温度低于180℃之前,仲碳原子最易发生接枝反应,其次是叔碳原子,当温度高于180℃后,伯碳原子、仲碳原子和叔碳原子的反应速率差不多。
For initiator B , when temperature is less than 180 ℃, MAH first reacts with secondary carbon of EB-block , secondly reacts with tertiary carbon ; when temperature is higher than 180 ℃, the reaction rate of MAH reacted primary , secondary , tertiary carbon are similar .
