Study for Soluble and Low-Refractive Index Hyperbranched Polymer Consisting of Fluoroadamantane
Soluble hyperbranched polymers consisting of numerous functional groups and end groups were prepared by one pot synthesis of divinyl monomers in a large amount of chain transfer agent (CT). The polymerization conditions for control of molecular weight with suppression of a gelation were investigated at various concentrations of reactants and molar ratio of CT to monomer. Hyperbranched polymers consisting of numerous functional groups and end groups were synthesized and molar ratio of end groups Hyperbranched polymers were evaluated by analysis of TOF MS and NMR. Transparent and low refractive index thin film was easily obtained by polymerization of divinyl fluoroadamantane monomers.
