如何用结构检索1，2 –聚丁二烯？结构式如下，有顺反式之分 此处是否有限制？为全同1，2 –聚丁二烯？ 还是间同1，2 –聚丁二烯？还是无定型？ 检索思路： 在SciFinder中聚合物结构的标引，或者是标引了聚合物的起始单体，或者是标引了聚合物的最终结构。 因此我们可以通过结构式绘制1，2 –聚丁二烯的起始物，1，3-丁二烯进行检索，并且，也需要使用 分子式检索（保证不漏检以最终结构标引的聚合物），最后将结果集合并。 CAS is a division of the American Chemical Society.

均聚物合成/制备检索技巧总结 如果需要用结构式检索均聚物合成、制备信息，则可用以下操作步骤： 直接绘制单体的结构式，并在执行检索之前，将条件设置为单组分、聚合物 获取到物质结果集后： A) 如果希望获取到精准的化学反应，则可通过物质获取化学反应，并限定物质在反应过程中的角色（产物） B) 如果希望获取最完整、全面的文献信息，则可通过物质获取文献信息，并将结果限定为工艺，制备等 CAS is a division of the American Chemical Society.
