A bisphenol epoxy resin was used as modifier to increase the heat resistance of condensed poly-nuclear aromatic (COPNA) resin. The basic properties of COPNA resin and modified resin were characterized by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (1H-NMR), vapor pressure osmometry (VPO) and elemental analysis (EA). Average structural parameters of resins...
As an industrial byproduct of oil refining, furfural extract oil from reduced-pressure route II with high aromatic content was used to prepare heat-resistant condensed polynuclear aromatic (COPNA) resin for the first time. The basic properties of furfural extract oil and the resultant COPNA resin were characterized by infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (1H-NMR),...
