新型紫外光固化大分子光引发剂的研究进展

Research progress of new type UV-curable macromolecular photoinitiators

综述了大分子光引发剂中改良型紫外光(UV)固化引发剂(有机硅、超支化聚合物改性)和新型UV固化引发剂(阳离子、可聚合和水性)在合成方法、结构性能等方面的最新研究进展。最后指出了大分子光引发剂仍存在的不足之处,并就其在阳离子-自由基混杂型、高Mr(相对分子质量)型及可见光型等方面的发展前景作了展望。

The latest research progress of some macromolecular photoinitiators, which were modified u ltraviolel （UV） curable initialors（such as organic silicon, and hyperbranched polymer modified initiators） and new type UV curable initiators（ such as cationic, polymerizable, and waterborne initiators ） ,was summarized in synthetic methods, and structure and properties. Finally, the still existing deficiencies in macromolecular photoinitiators were indiealed, and its development prospect was expected in cationic-free radicals mixed types, high Mr （molecular weight） types and visible light types.
