Crystallization of Biobased Long-Chain Aliphatic Polyesters as Sustainable Polymers: Effects of the Diol Structure in the Monomer Unit.

ABSTRACT: Biobased polyesters, recyclable sustainable polymers derived from renewable feedstock, are promising alternatives to petroleum-based polymers. The crystallization behavior, crystal structure, and supramolecular structures of a series of biobased long-chain aliphatic polyesters, consisting of a diester of 10-undecenoic acid with isosorbide (IS), isomannide (IM), and butanediol (BD) as the midsegments, were studied by various scattering methods and Raman spectroscopy. Polyesters containing butanediol-type midsegments (C₁₈BD) participated in the crystallization by being incorporated into the orthorhombic polyethylene crystal lamellae. The polyesters containing isosorbide- and isomannide-type midsegments (C₁₈IS, C₁₈IM) were excluded from the crystal lamellae an
