引言我厂丁二烯聚合使用的溶剂油(67～90℃),系炼油厂铂重整抽余油。该油中含有微量烯烃杂质,其碘值一般在0.2～0.5(克/100克)左右,最高可达1.0以上。它可以影响聚合催化剂活性,使聚合转化率下降;同时也是导致胶团生成、凝胶增高等影响橡胶质量稳定的不利因素之一。但不同产地的溶剂油,其烯烃杂质对聚合的影响程度亦不同,因此,有必要对其具体杂质组分进行
INTRODUCTION Solvent oil (67 ~ 90 ℃) used in the polymerization of butadiene in our factory is a platinum remineral rape oil refinery. The oil contains traces of olefin impurities, the iodine value is generally about 0.2 ~ 0.5 (g / 100 grams), up to 1.0 or more. It can affect the activity of the polymerization catalyst, so that the polymerization conversion rate; but also lead to the formation of micelles, increased gel and other factors that affect the quality of the rubber stability. However, the solvent oil from different areas, the olefin impurities on the degree of polymerization are also different, therefore, it is necessary for its specific impurity components
