金融界2025年7月12日消息，国家知识产权局信息显示，国科广化（南雄）新材料研究院有限公司;国科广化精细化工孵化器（南雄）有限公司;中科院广州化学有限公司;国科广化韶关新材料研究院申请一项名为“一种高分子量MQ硅树脂及其制备方法与应用”的专利，公开号CN120289793A，申请日期为2025年04月。
专利摘要显示，本发明属于有机硅材料合成技术领域，公开了一种高分子量MQ硅树脂及其制备方法与应用。在惰性气氛保护下，将Q单元单体、M单元单体与有机酸混合，加入酸性催化剂，进行水解缩合反应，初步形成含M单元和Q单元的三维网络结构；向反应体系中先滴加乙烯基封端剂反应，后滴加含氢封端剂继续反应，将乙烯基封端剂和含氢封端剂接入Q单元上，待反应结束后，调节反应体系pH至中性，分离收集有机相，加入铂催化剂进行硅氢加成反应，反应结束后经后处理，固化，得到高分子量MQ硅树脂。
