| description | The invention belongs to the field of functional polymer materials, and particularly relates to a synthesis method of PHS resin with narrow molecular weight distribution, which has the beneficial effects that 1, continuous flow chemical synthesis of the PHS resin is carried out by using a micro-channel reaction system; and 2, initiating by using a composite initiator compounded by azo and polyfunctional peroxide initiators. The problems of poor production safety, unstable product quality and the like caused by thermal instability in the polymerization process are solved. Meanwhile, PDI of the obtained PHS resin is smaller than or equal to 1.2, metal impurities are smaller than or equal to 0.5 ppb, and the PHS resin can be suitable for preparation of KrF photoresist thin glue.
本申请属于功能高分子材料领域，具体涉及一种窄分子量分布的PHS类树脂的合成方法，有益之处在于：1、使用微通道反应系统进行PHS类树脂的连续流动化学合成。2、使用偶氮类与多官能度过氧类引发剂复合的复合引发剂引发。解决了聚合过程中热不稳定问题带来的生产安全性差、产品质量不稳定等问题。同时所得PHS类树脂的PDI≤1.2，金属杂质≤0.5ppb，可以适用于KrF光刻胶薄胶的制备中。 |
