The purpose of this study was to characterize the structure of polyethyleneglycol methacrylate and investigate their photochemical initiated polymerization. 合成了一系列新型的具有光引发聚合反应活性的单体:不同分子量的聚乙二醇的双甲基丙烯酸酯。
UV curing is used to induce photochemical polymerization or crosslinking of a monomer, prepolymer formulation containing a certain type of unsaturation, such as an acrylic group, and an appropriate initiator. 采用UV固化技术可以使含有不饱和官能团的活性单体、预聚物在光引发剂的作用下进行光聚合反应发生交联。
The recording mechanism of photopolymer is the photochemical reaction. The illumination makes the small molecules polymerize and form polymer distribution corresponding to the exposure energy. Generally, polymerization brings the volume change of material. 光致聚合物的存储机理是光化学反应,由于光照使得材料中小分子发生聚合反应而形成与光照强度相对应的聚合物分布。通常聚合反应的发生会引起材料体积的变化。
