一般描述
聚(丙二醇)（PPG）是一种生物相容性聚合物，被广泛用作制备生物医学材料的前体。低温时可溶于水，高温时不溶于水。
应用
聚(丙二醇)可用作：
- 前体，用于合成用于各种生物医学应用的多嵌段热响应智能聚合物。PPG 的存在是这些聚合物具有热敏性的主要原因。例如，它可用于合成聚酯聚氨酯。
- 用于剑麻纤维的表面改性，以提高成核能力。

Despite its common usage in vertebral augmentation procedures (VAPs), shortcomings of commercial polymethylmethacrylate (PMMA) still remain. Accordingly, injectable and biodegradable composite cements, which are composed of poly(propylene fumarate)/α-tricalcium/hydroxyapatite (PPF/α-TCP/HAP) and PPF/tetracalcium phosphate/dicalcium phosphate (PPF/TtCP/DCP), were developed. A porcine model was
