摘要
以甲基丙烯酸烯丙酯和1,1,5,5-四甲基-3,3-二苯基三硅氧烷为原料,硅氢加成得到含苯基硅氧烷的丙烯酸酯单体。采用核磁(1H-NMR)法表征了产物的封端基团,超高效液相色谱三重串联飞行时间质谱法(UPLC-QTof-MS)对不同封端基团产物的具体结构进行分析,鉴定出甲基丙烯酸-3-(1,1,5,5-四甲基-3,3-二苯基-5-甲基丙烯酰氧基三硅氧基)丙酯、1,1,5,5-四甲基-1,5-二(γ-甲基丙烯酰氧丙基)-3,3-二苯基三硅氧烷和甲基丙烯酸-3-(1,1,5,5-四甲基-5-丙基-3,3-二苯基三硅氧基)丙酯3个主要组分。建立了有机硅改性丙烯酸酯类功能材料的定性分析方法,对其进一步开发利用及其反应机理研究方面具有重要的指导意义。
Phenyl siloxane-containing acrylate monomer was prepared through hydrosilylation of allyl methacrylate with 1, 1, 5, 5-tetramethyl-3, 3-diphenyltrisiloxane. The end-groups of product were analyzed by nuclear magnetic resonance （1H -NMR）. The specific structures with different endgroups were analyzed by triple ultra performance liquid chromatography - time of flight mass speetrometry（UPLC - QTof - MS）. And the results showed that there were three main components, including seperately 3-（5-methacryloyloxy-1, 1, 5, 5-tetramethyl-3, 3-diphenyhrisiloxanyl）propyl methacrylate, 1, 5-bis（γ-methacryloxypropyl）-1, 1, 5, 5-tetramethyl-3, 3-diphenyl trisiloxane and 3-（1, 1, 5, 5-tetramethyl-3, 3-diphenyl-5-propyltrisiloxanyl）propyl methacrylate. In this paper, the qualitative analysis method of acrylate modified by silicone was established, which has an important guiding significance for its further development and reaction mechanism.
