摘要： 合成了树枝状(甲基)丙烯酸化醚酰胺低聚物,采用拉曼光谱、光-差热分析和动态力学热分析方法对其紫外光固化动力学和固化膜热机械性能进行了研究.结果表明,这种树枝状低聚物在紫外光照下双键转化率可达80%以上,且其最大反应速率、固化膜的软化温度和玻璃化转变温度随双键浓度的增大而提高.

Abstract: Dendritic polymers have received increasing interests from polymer scientists because of the unique structural characteristics, synthetic methods as well as application fields. The (meth)acrylated dendritic poly(ether-amide)s were synthesized by a divergent manner and characterized by 1H NMR, VPOand FTIRmeasurements. Their UVcuring properties were investigated by Raman, Photo-DSCand DM-TAmeasurements. Over 80% of unsaturation conversion has been obtained for the systems in the presence of a photoinitiator under UVirradiation, and the polymerization rate at peak maximum was promoted with increasing the concentration of double bonds. The softening and glass transition temperatures of their UVcured films were also promoted with increasing the concentration of double bonds.

Key words: Dendrimer, Poly(ether-amide), UV curing, Kinetics, Thermomechanical property
