  摘要：

  多种二甲基取代的噻喹喔啉是通过2-巯基苯甲酸与邻-, 中-, 或对-二甲苯在硫酸中的缩合反应制备的。其中一些是新化合物（5，11，12和13）。即，从邻二甲苯中形成了1,2-二甲基（11），2,3-二甲基（12）和3,4-二甲基噻喹喔啉（13），产率分别为9.3%、37.1%和12.8%。通过相同的缩合反应，从中二甲苯和对二甲苯分别获得了2,4-二甲基噻喹喔啉（4）和1,4-二甲基噻喹喔啉（9）。根据光谱研究和与通过另一合成路径（即苯基硫代苯甲酸的环化反应）获得的认证材料的比较，确认了这些化合物的结构。

  An adhesive sheet for dicing comprising a base film provided at least one surface thereof with an adhesive layer, wherein the base film comprises an olefinic thermoplastic elastomer comprising propylene and ethylene and/or &agr;-olefin including 4 to 8 carbon atoms as polymerization components, and the peak melting temperature of the olefinic thermoplastic elastomer is 120° C. or more, is free of economical disadvantages with less reduction in the quality level of products and less generation of fibrous off-cuts during dicing. In particular, fibrous off-cuts occur less during dicing when the base film contains a crystal-nucleating agent. Further, generation of chippings during dicing can be prevented by incorporation of an ethylene series polymer into the base film.

  一种用于切割的粘合片，包括至少一表面带有粘合层的基膜，其中基膜包括丙烯和乙烯和/或α-烯烃（4-8个碳原子）作为聚合组分的烯烃热塑性弹性体，且烯烃热塑性弹性体的峰值熔点为120℃或更高，不会产生经济上的不利影响，同时产品质量水平降低和切割过程中纤维碎屑的生成较少。特别是，在基膜中含有结晶成核剂时，切割过程中的纤维碎屑会更少。此外，通过将乙烯系聚合物并入基膜中，可以防止切割过程中产生切屑。
