New furan based amino plastics: synthesis, properties and applications

The possibilities of fabrication and properties of new furan-containing polymers based on 5-hydroxymethylfurfural (5-HMF) and nitrogen-containing co-monomers (urea and melamine) have been studied. Two series of polymers, namely, 5-HMF-melamine and 5-HMF-urea at different ratios of the furan component: melamine (urea) were obtained. The effect of temperature in the range of 80–180 °C on the degree of cross-linking of polymers was studied. The thermostability of polymers was investigated by the TGA method. The polymers were tested for fire resistance according to GOST 28157-89 standard. It is demonstrated that obtained materials show increased heat and fire resistance in comparison to similar urea- and melamine-formaldehyde resins. It is recommended to use the developed polymers as non-combustible heat-insulating materials.
