摘要/Abstract

摘要： 介绍了一个制备聚氨酯丙烯酸酯(PUA)膜的高分子综合化学实验。实验分为聚氨酯丙烯酸酯预聚体的合成和紫外光固化成膜两个阶段。在预聚体合成阶段，甲苯二异氰酸酯(TDI)先后与聚醚二元醇和丙烯酸羟乙酯反应，合成聚氨酯丙烯酸酯预聚物。第二阶段在预聚物中加入活性稀释剂、流平剂、交联剂、引发剂等制备光敏树脂，涂膜并进行光固化。实验包括理论知识学习、材料性能测试和实验技能练习，适合高年级本科生或研究生实验教学，有助于提升学生的综合实验能力和对高分子材料的认知。

Abstract: This article presents a comprehensive polymer chemistry experiment on the preparation of polyurethane acrylate (PUA) films. The experiment is divided into two stages: the synthesis of the PUA prepolymer and the formation of UV-curable films. In the prepolymer synthesis stage, toluene diisocyanate (TDI) reacts sequentially with polyether diol and hydroxyethyl acrylate to produce the PUA prepolymer. In the second stage, the prepolymer is formulated into a photosensitive resin by adding reactive diluents, leveling agents, crosslinkers, and photoinitiators. The mixture is then coated and cured under ultraviolet (UV) light. The experiment encompasses theoretical knowledge learning, material performance testing, and experimental skill practice. It is suitable for experimental teaching of senior undergraduate or graduate students and helps enhance students’ comprehensive experimental abilities and understanding of polymer materials.

Key words: Polyurethane acrylate (PUA), Photosensitive resin, UV curing, Thin films
