(英) Hyperbranched Polymer through Initiator-Fragment Incorporation Radical Copolymerization of Divinyl Adipate with Allyl Acetate: Synthesis, Characterization, Dye Solubilization, Metal-Nanoparticle Stabilization, and Porous Film Formation

(英) The copolymerization of divinyl adipate (DVA) as an effective cross-linker with allyl acetate (AAc) as a degradative chain transfer reagent was carried out at 70 and 80 °C in benzene using dimethyl 2,2 -azobisisobutyrate (MAIB) of high concentrations as initiator. When the MAIB concentration as high as 0.60 mol/L was used, the copolymerization of DVA (0.20 mol/L) and AAc (0.50 mol/L) proceeded homogeneously without any gelation to give soluble copolymers in a yield of about 30% based on the total weight of DVA, AAc, and MAIB. The copolymer formed in the copolymerization at 80 °C for 6 h consisted of the DVA units with (3 mol %) and without (24 mol %) double bond, the AAc unit (35 mol %), and the methoxycarbonylpropyl group (38 mol %) from MAIB. Such a large fraction of the incorporated initiator-fragment as terminal group indicates that the copolymer has a hyperbranched structure. The copolymer exhibited potentials in solubilization of Rhodamine 6G as a dye probe and stabilization of metal nanoparticles. A porous film was obtained simply by casting a copolymer solution in THF.
