Poly(1,20-eicosanediyl 2,5-furandicarboxylate), a biodegradable polyester from renewable resources

resumo

Furanic-very-long-aliphatic polyester based on 2,5-furandicarboxylic acid and 1,20-eicosanediol was introduced as a new polymer from renewable resources that is biodegradable. This poly (1,20-eicosanediyl 2,5-furandicarboxylate) (PE20F) was extensively characterised by means of FTIR, H-1 and C-13 NMR, SEC, DSC, TGA, sorption experiments, water contact angles and biodegradation tests. PE20F has a melting temperature of 107 degrees C, a glass transition around 7 degrees C and moreover has a water contact angle of 96 degrees, but nevertheless PE20F biodegraded.
