A novel bio-based autocatalytic amide-type phthalonitrile monomer: Synthesis, curing kinetics and thermal properties
A bio-based bisphenol compound (DFA) was prepared using bisphenolic acid and furfurylamine in biomass as raw materials. Then, a bio-based amide phthalonitrile monomer (DFAP) was obtained in an environmentally friendly solvent. Nuclear magnetic resonance and Fourier transform infrared spectroscopy (FT-IR) proved the successful synthesis of DFA and DFAP. The curing behavior and curing kinetics of the polymer were studied using FT-IR and differential scanning calorimetry. Calculate the activation energy using the isoconversion method. The SB(m, n) autocatalytic reaction model describing the curing process of poly(DFAP) was modified and fitted by introducing the variable activation energy model. The thermal stability, thermomechanical properties and processing properties of the resin were studied using technologies such as thermogravimetric analyzer, dynamic mechanical analyzer and rheometer. The results show that the prepolymer has a wide processing window and a low melt viscosity. Poly(DFAP) has a high glass transition temperature and excellent thermal stability.
期刊介绍：
European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas:
Polymer synthesis and functionalization
• Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers.
Stimuli-responsive polymers
• Including shape memory and self-healing polymers.
Supramolecular polymers and self-assembly
• Molecular recognition and higher order polymer structures.
Renewable and sustainable polymers
• Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites.
Polymers at interfaces and surfaces
• Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications.
Biomedical applications and nanomedicine
• Polymers for regenerative medicine, drug delivery molecular release and gene therapy
The scope of European Polymer Journal no longer includes Polymer Physics.
