Abstract

This invention provides a chlorinated poly(propylene carbonate) and the preparation method thereof, the chlorinated poly(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 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 chlorinated poly(propylene carbonate) materials.
