Materials with shape memory effect from bio-based raw materials, which exhibit good mechanical and thermal properties, are now often topic of research. First part is synthesis of bio-based benzoxazine which is a key component in combination with epoxy resin. Benzoxazine monomer is characterized with Fourier transform infrared spectroscopy (FTIR), magnetic resonance spectroscopy (NMR) and differential dynamic calorimetry (DSC). NMR method confirmed the presence of benzoxazine ring. In order to improve the thermal mechanical properties of the benzoxazine monomer, copolymer with resorcinol diglicidil ether was prepared in different ratios. Using DSC analysis, thermal properties of copolymer crosslinking were determined. First exothermic peak represents copolymerization of benzoxazine monomer and epoxy resin. The second peak represents homopolymerization of residual resorcinol diglicidil ether. Entalphy increases with a higher percentage of epoxy resin in the copolymer. Dynamic mechanical analysis (DMA) confirmed temperature of glass transition (Tg) for benzoxazine monomer at 81,7 °C. RS-BOX : RS-EP copolymers exhibit Tg in range between 60 °C and 80 °C. The lower the proportion of benzoxazine in the copolymer, the lower the Tg. With a higher epoxide content in the copolymer, the elastic modulus increases. The effect of shape memory was confirmed in preliminary tests by a bending test at ratios of 33 : 67, 50 : 50, and 67 : 33. Shape recovery ratio Rr showed that all samples returned to its original shape but needed more relaxation time. The shape fixity ratio Rf ranges between 95 % and 99 %. The higher ratio of epoxide in the copolymer represents higher rigidity. The higher higher ratio of benzoxazine also shows insufficient structural strength to maintain the shape. The most promising results were shown by RS-BOX : RS-EP molar ratio 50 : 50 due to the best Rr, sample homogeneity and mechanical properties in practice. Cyclic load of 50 : 50 ratio at a load angle of 120° showed a good shape fixity ratio between 98 % and 99 %. The shape recovery ratio of restored sample over each cycle indicated a slight loss of its shape memory function. For practical purposes benzoxazine monomer and copolymer RS-BOX : RS-EP still show excessive fragility, which may be a starting point for further research and improvements.
