Abstract:
      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 end groups were analyzed by triple ultra performance liquid chromatography-time of flight mass spectrometry(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-diphenyltrisiloxanyl)-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.
