  The backbone of poly(butylene terephthalate) (PBT) was modified with 2,4:3,5‐di‐O‐methylene‐D‐glucitol (Glux) using solid‐state modification (SSM). The obtained copolyesters proved to have a non‐random overall chemical microstructure. The thermal properties of these semicrystalline, block‐like, Glux‐based materials were extraordinary, showing higher melting points, and glass transition temperatures

  聚对苯二甲酸丁二酯（PBT）的骨架用2,4：3,5-二-O-亚甲基D改性使用固态修饰（SSM）的葡萄糖醇（Glux）。所获得的共聚酯被证明具有非随机的整体化学微观结构。与由SSM制备的其他基于糖的共聚酯相比，这些半结晶，块状，基于Glux的材料具有出色的热性能，显示出更高的熔点和玻璃化转变温度。这些卓越的热性能是Glux固有的刚性结构以及熔体中Glux基共聚酯的嵌段状化学微观结构相对较慢的随机化的直接结果。SSM被证明是用于制备具有优异热性能的部分生物基共聚酯的多功能工具。©2013 Wiley Periodicals，Inc.

  Provided herein are polyesters that comprise (i) monomer units derived from sugar-based bicyclic diol; (ii) monomer units derived from an unsaturated aliphatic diacid; and (iii) monomer units derived from a saturated aliphatic diacid. The monomer units derived from the ethylenically unsaturated aliphatic diacid can be present in an amount of from greater than 0 mole % to 40 mole % of the polyester. These polyesters can be formed into articles using additive manufacturing methods. The resulting articles can be biocompatible, resorbable over a span of from 3 months to 12 months following implantation in the human body, and can exhibit desirable mechanical properties for applications, including porosity and elasticity.
