In this study, the epoxidation of styrene-isoprene-styr en e triblock copolymers (SIS) by an in situ generated peracid method was discussed .

利过甲酸对热塑弹性体SIS进行环改性,合成了环SIS(ESIS)。

In this paper, the protection measures of carbohydrate during pulp TCF bleaching, such as oxygen, ozone, peroxide, peracid and photochemistry reaction of bleaching, were respectively.

摘要本文综述了纸浆的气漂白、臭漂白、过漂白、光催漂白、过酸漂白中碳水合物的保护措施。
