Today, academic and industrial research in the field of plastic packaging is strongly oriented towards biobased alternatives to petroleum-derived plastics. Among biobased plastic materials, aliphatic polyesters have attracted considerable attention as they combine reasonable costs with interesting physical and chemical properties. Within the polyester class, poly(alkylene 1,4-trans-cyclohexanedicarboxilate)s offer various advantages: the presence of an aliphatic ring along the polymer backbone enables the material to have good thermal stability and mechanical properties maintaining the biodegradability[1]. Another biobased building block that has attained high notoriety in these last years is 2,5-Furandicarboxylic acid (FDCA) [2]. The chemical structure, thermal stability and aromatic nature of FDCA make this diacid especially suitable for replacing terephthalic acid in packaging applications. In this view, in the present work we have synthesized a novel class of biobased poly(propylene cyclohexane dicarboxylate/furanoate) (PPFPPCEt) multiblock copolyesters through reactive blending.

Abstract
Today, academic and industrial research in the field of plastic packaging is strongly oriented towards biobased alternatives to petroleum-derived plastics. Among biobased plastic materials, aliphatic polyesters have attracted considerable attention as they combine reasonable costs with interesting physical and chemical properties. Within the polyester class, poly(alkylene 1,4-trans-cyclohexanedicarboxilate)s offer various advantages: the presence of an aliphatic ring along the polymer backbone enables the material to have good thermal stability and mechanical properties maintaining the biodegradability[1]. Another biobased building block that has attained high notoriety in these last years is 2,5-Furandicarboxylic acid (FDCA) [2]. The chemical structure, thermal stability and aromatic nature of FDCA make this diacid especially suitable for replacing terephthalic acid in packaging applications. In this view, in the present work we have synthesized a novel class of biobased poly(propylene cyclohexane dicarboxylate/furanoate) (PPFPPCEt) multiblock copolyesters through reactive blending.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
