Abstract
Functional polymer, “Poly Di(pyridin-2-yl)methyl acrylate” (PDPyMA) was synthesized successfully, which could be served as supporters for different metals to do different catalytic reactions. In the reaction of suzuki-miyaura coupling, it could be a good supporter for ten cycles, with low yield subtraction at every circle. The condition of catalytic reactions must “not” in acid/basic aqueous, or the functional polymer“ PDPyMA” would be hydrolysis into poly acrylic acid (PAA) losing the function of being supporters for metals. Different metals including copper and cobalt metals coordinated to functional monomer “Di(pyridin-2-yl)methyl acrylate” (DPyMA) were characterized by X-ray in order to build up database of different structures of complexes. Hydrosilylation is widely used industrially for the preparation of monomers with silicon-carbon bonds and for producing crosslinked polymers. Inhibitors are often used in industry to control the platinum-mediated addition reaction of curable systems. The addition of inhibitors prevents hydrosilylation at premix period (low temperature) while permitting rapid reaction at elevated temperature (Curing period). Dimethyl fumarate would be a good candidate for company with longer premix time (8 hours) and shorter curing time (45 minutes). Water soluble CoII(salophene) complexes was used to do acrylic acid and 4-vinyl pyridine controlled radical polymerization. The effect of controlling acrylic acid polymerization was not as good as I expected. CoII(salophene) would be affected by hydroxyl of acrylic acid and led to poor control. In the 4-vinyl pyridine controlled radical polymerization, 1, 1, 1, 3, 3, 3-hexafluoro-2-propanol was used as solvent, which can interact with 4-vinyl pyridine via hydrogen bonding and reduce the phenomenon of binding to the CoII(salophene) catalyst.
