中文摘要：

利用四甲基环四硅氧烷（D4^H）与4-（β-羟基-γ-烯丙氧）丙氧基-2-羟基二苯甲酮（MUV-O）、烯丙基缩水甘油醚（AGE）、烯丙基聚氧乙烯醚（CG-5）的硅氢化加成反应，合成了一种分子中携带二苯甲酮衍生物、聚醚以及环氧基团的有机硅抗紫外整理剂DMUV-O．用红外光谱、核磁共振氢谱、紫外光谱等仪器对其进行了结构表征．DMUV—O用于棉织物后整理的结果表明，DMUV-O对波长为243．6nm、289．2nm、325．0nm的紫外光有强吸收作用，并能改善织物的紫外吸收性能，能明显降低织物的弯曲刚度，增加织物的柔软性和吸湿性，对织物的白度和透气性影响不大．

英文摘要：

An anti-UV finishing agent DMUV-O bearing benzophenone, polyether and epoxy functional groups was synthesized by hydrosilylation addition reaction of tetramethylsiloxane （D4^H） with 2-hydroxy-4-（β-hydro- xy-γ-allyloxy）propyloxy benzophenone （MUV-O）, allyl glycidyl ether （AGE） and allyl polyoxyethylene ether （CG- 5）. The chemical structure of DMUV-O was characterized by IR, ^1H-NMR and Ultraviolet spectrum. The DMUV- O application study was carried out with cotton fabric. The results indicated that DMUV-O had an intensive UV- absorbing capacity at wavelengths of 243.6 nm,289.2 nm,325.0 nm, respectively. The cotton fabrics treated by DMUV-O showed a reduced bending rigidity, improved softness and water-absorbing property. DMUV-O could obviously improve the UV-absorbing performance of fabric and had little influence on the whiteness and air permeability of fabric.
