Beschreibung
Zusammenfassung:	The invention relates to an alkali-soluble polymer for preparing an LDI dry film and a preparation method of the alkali-soluble polymer. The side chain of the alkali-soluble polymer provided by the invention has an oxetane group; and the polymerization unit containing the oxetane group accounts for 1-65% of the alkali-soluble polymer in percentage by mass. The alkali-soluble polymer disclosed by the invention is prepared by adopting a free radical polymerization method. The alkali-soluble polymer is used for preparing the LDI dry film, the LDI dry film prepared by matching the alkali-soluble polymer and a cationic initiator is directly exposed through laser, and compared with the LDI dry film in the prior art, the LDI dry film has good sensitivity, resolution, sealing performance, hole covering rate and resist shape. 本发明涉及一种用于制备LDI干膜的碱溶性聚合物及其制备方法。根据本发明的碱溶性聚合物侧链具有氧杂环丁烷基团；且含氧杂环丁烷基团的聚合单元在碱溶性聚合物中占以质量百分比计的1~65%。本发明采用了自由基聚合法制备得到了本发明的碱溶性聚合物。将本发明的碱溶性聚合物用于制备LDI干膜，通过激光对采用碱溶性聚合物和阳离子引发剂配合制备得到的LDI干膜进行直接曝光，LDI干膜相对于现有技术的LDI
