Abstract
Acrylonitrile(AN)-Vinyl acetate (VAc) copolymers (AN/VAc) were synthesized by redox polymerization and microencapsulated phase change materials (MicroPCMs) were incorporated at the polymerization step. The effect of VAc monomers and/or the MicroPCMs on composition, melting point (T m ), exothermic peak value (T d), average molecular weight (M η ), crystallinity of the copolymers were examined by Fourier Transform Infrared Spectroscopy (FTIR), Elementary Analysis, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TG), Ubbelohde viscosimeter and X-ray Diffraction (XRD). The compositions of the AN/VAc agreed well with the feed ratios. The melting peak shifted to a lower temperature (267 °C) with increasing concentration of VAc monomers and/or MicroPCMs, while the exothermic peak shifted to the higher temperature (324 °C). The average molecular weight of the copolymer was approximately 31,000. The crystallinity of the copolymers decreased with increasing content of VAc monomers and/or MicroPCMs.
