摘　　要：在实际生产中,原材料中带有的杂质种类繁多,这些影响聚合反应的杂质可分为为两类:一类是急性杂质,如水、醇类、TBC。另一类是慢性杂质,如甲基乙炔、丙二烯等。本文主要分析影响丁苯透明抗冲树脂熔指因素,主要从原料中水和阻聚剂TBC的含量、丁基锂加入量、聚合物分子量大小与分布、苯乙烯丁二烯排列无归链段等进行分析,研究这些因素对熔指的影响情况对熔指的控制有着重要意义。There are many types of impurities in raw materials in actual production.These impurities which affect the polymerization reaction can be divided into two categories:one is acute impurities,such as water,alcohols,and TBC.The other is chronic impurities,such as methyl acetylene,allene,and so on.The factors which affected the melt index of styrene butadiene transparent impact resin were analyzed.These factors mainly contained the content of water and polymerization inhibitor TBC in the raw materials,the amount of butyl lithium added,the size and distribution of polymer molecular weight,and the arrangement of styrene butadiene non-returning segments.The influence of these factors on the melting index is of great significance to the control of the melting index was analyzed.
