Implementing plant-derived isosorbide and isomannide as comonomers for polyester synthesis: Effects of crystallization properties on optical properties

This article describes the implementation of plant‐derived isosorbide (IS) and isomannide (IM) in the copolymerization modification of poly(ethylene terephthalate). The effects of the two comonomers on the optical, crystallization, and thermal properties of the resulting copolyesters were studied using the following analytical methods: proton nuclear magnetic resonance; differential scanning calorimetry; X‐ray diffraction; thermogravimetry; and...
