10 聚合物检索——分子式检索 聚合物的分子式表现形式 分子式中带有括号 括号外为n,嵌段聚合物(有首尾端或无首尾段都可)
有端基嵌段聚合物分子式:(C6H10O2)n C3H4O2 无端基嵌段聚合物分子式:(C12 H12 O4)n 括号外为x,对于均聚物和共聚物,将以单体进行标引,聚合度不影响标引 共聚物:(C2 H4 . C2 F4)x 均聚物:(C2H4)x CAS is a division of the American Chemical Society. Copyright 2016 American Chemical Society. All rights reserved.

11 (C2 H4 . C2 F4)x——SciFinder检索结果

13 用结构限定 CAS is a division of the American Chemical Society. Copyright 2016 American Chemical Society. All rights reserved.

14 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. Copyright 2016 American Chemical Society. All rights reserved.

15 在结构编辑器中绘制聚合物的起始物单体 CAS is a division of the American Chemical Society. Copyright 2016 American Chemical Society. All rights reserved.

16 在结果集中找到所需聚合物 无定型 间同 全同 CAS is a division of the American Chemical Society. Copyright 2016 American Chemical Society. All rights reserved.

17 使用分子式检索(C4H6)x检索聚合物 CAS is a division of the American Chemical Society. Copyright 2016 American Chemical Society. All rights reserved.

18 浏览分子式检索(C4H6)x的结果集,找到符合要求的结果

22 总结 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。
使用结构式检索均聚物,需要绘制该聚合物的起始物 同时使用分子式检索(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. Copyright 2016 American Chemical Society. All rights reserved.

23 提纲 聚合物结构检索 聚合物分子式检索 聚合物反应检索 检索所有包含下列结构特征的乙烯作为单体的均聚物的反应(文献)

24 检索案例:检索所有包含下列结构特征的乙烯作为单体的均聚物的反应(文献)
检索思路: 从结构检索出发,经过限定后,得到聚合物物质结果集 方案一:由物质获得反应,再获得相关合成制备文献; 方案二:由物质获得文献,再通过文献检索结果处理工具精选文献 CAS is a division of the American Chemical Society Copyright 2016 American Chemical Society. All rights reserved.

25 打开物质检索结构编辑器, 绘制起始物结构, 使用可变基团工具, R基团定义工具, 环锁定工具 原子锁定工具对结构进行限定。 选择亚结构检索

38 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. Copyright 2016 American Chemical Society. All rights reserved.
