New Strategy toward Novel Hyperbranched Phenol-Formaldehyde Resin: Synthesis, Characterization and Curing Study
Novel hyperbranched phenol-formaldehyde (HBPF) resin 1 has been prepared for the first time. Thorough characterizations (FT-IR, NMR, HPLC, MALDI-TOF MS and elemental analyses and rheological flow behavior) were performed to ascertain the structure of HBPF 1. The condensationcuring event of HBPF with diglycidylether of bisphenol-A (DGEBA) has been studied by differential scanning calorimetry (DSC) technique.
