Styrene-free unsaturated polyesters for hemp fibre composites
N-vinyl-2-pyrrolidone (NVP) and tri(ethylene glycol) divinyl ether (TDE) are utilized as reactive diluents to replace carcinogenic styrene (St) during the formulation of unsaturated polyester (UPE) resins. The processability and thermomechanical properties of the UPE resin-containing hemp fibre composites are evaluated. Both NVP-UPE and TDE-UPE resins exhibit better miscibility than the St-UPE resin...
