摘要：本发明提供一种氯化聚碳酸亚丙酯及其制备方法，该氯化聚碳酸亚丙酯的结构如式（I）所示。相较于现有聚碳酸亚丙酯，氯化聚碳酸亚丙酯分子中含有氯原子，电负性更高，能够增强其与其他极性材料之间的相互作用，因此可广泛用作相容剂、粘结剂、涂料、油墨等。引入氯原子后，氯化聚碳酸亚丙酯分子内部可形成氢键作用，使其加工性能与力学性能同步提升。除此之外，氯原子还能够改善氯化聚碳酸亚丙酯材料的阻燃性能。

Abstract: This invention provides a chlorinated poly(propylene carbonate) and the preparation method thereof, the chlorinatedpoly(propylene carbonate) is as represented by formula (I)Compared to the prior poly(propylene carbonate)S, the chlorinated poly(propylene carbonate) has relatively stronger electronegativity due to the presence of chlorine atoms and the interaction of the chlorinated poly(propylene carbonate) with other polar materials can be enhanced, so that it can bewidely used as a compatilizer, a binder, a paint, an ink, and the like. After the introduction of chlorine atoms, hydrogen bond interaction is generated within the chlorinated poly (propylene carbonate), so that its processability and mechanical properties are both improved. Furthermore, the chlorine atom may improve the flame retardancy of chlorinated poly(propylene carbonate) materials.
