Preparation of P(DVB-co-MPS) Inorganic-Organic Hybrid Polymer Microspheres

摘要

A novel inorganic-organic hybrid polymer microspheres were facilely synthesised by distillation-precipitation polymerization in absence of any stabilizer or surfcant. The process were conducted with [3-(Methacryloyloxy) propyl] trimethoxysilan (MPS) as monomer, divinyl benzene (DVB) as cross linking agent and azobisisobutyronitrile (AIBN) as initator in acetonitrile. A series of silica nanoparticles were prepared in accordance with the volume ratio of MPS, which was varied in the range of 10% to 50%. However, there is no microspheres obtained while the ratio up to 50%. Products were charactered by transmission electron micrograph (TEM) and fourier transform infrared spectroscopy (FTIR). We may infer it from the constructional formular and FTIR graph that there were silicon hydroxyl remained in the microsphere surface.
