摘要：本发明提供了一种氯化聚丙撑碳酸酯及其制备方法，该氯化聚丙撑碳酸酯如式（I）所示。与现有聚丙撑碳酸酯相比，氯化聚丙撑碳酸酯由于氯原子的存在，使其具有较强的电负性，可增强氯化聚丙撑碳酸酯与其他极性材料的相互作用，从而可作为相容剂、粘合剂、涂料、油墨等得到广泛的应用；引入氯原子后可使氯化聚丙撑碳酸酯之间产生氢键相互作用，进而使其的加工性能和力学性能均得到改善，且氯原子可改善氯化聚丙撑碳酸酯材料的阻燃性能。

Abstract：This invention provides a chlorinated poly(propylene car-bonate) and the preparation method thereof, the chlorinatedpoly(propylene carbonate) is as represented by formula (I).

Compared to the prior poly(propylene carbonate)s, the chlo-rinated poly(propylene carbonate) has relatively strongerelectronegativity 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 be widely 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 chlori-nated poly(propylene carbonate) materials.
