间过氧化氢二异丙苯在丁苯橡胶装置上的应用
王湘水
摘要:以间过氧化氢二异丙苯(m-DIP)替代对过氧化氢二异丙苯(p-DIP)作引发体系
的氧化剂,进行了丁苯橡胶的小试和生产装置试验。结果表明,所生产出的低温乳聚丁
苯橡胶性能符合GB12824—91要求;与p-DIP相比,使用m-DIP可进一步提高后期聚合反
应速率,从而降低氧化还原体系用量和DIP单耗。

Abstract:The bench test and the production test of styrene-butadiene
rubber were studied with 1,3-diisopropylbenzene hydroperoxide as the oxidant in
initiation system instead of 1,4-diisopropylbenzene hydroperoxide.The results showed
that
the properties of emulsion polymerized styrene- butadiene rubber accorded with the
demands of GB 12824—91.The rate of polymerization was higher than that with 1,4-diisopropylbenzene
hydroperoxide and the consumption of oxidation-reduction system was decreased.
Keywords:styrene-butadiene rubber;diisopropylbenzene
hydroperoxide;oxidant;consumption
