摘要：首次在实验室对二氧化碳与环氧丙烷共聚产物聚碳酸丙烯酯（PPC）进行氯化。核磁共振波谱和离子色谱测试表明，氯原子成功引入PPC聚合物链，这种新材料被命名为氯化聚碳酸丙烯酯（CPPC）。值得注意的是，PPC氯化反应条件相当温和，可在工业水平简便实现。更重要的是，与PPC相比，CPPC在溶解性、润湿性、粘接性和气体阻隔性等方面具有许多更优异的性能。例如，CPPC作为热熔胶对木材、不锈钢和玻璃的粘接强度几乎是PPC的4倍；CPPC的氧气渗透系数比PPC降低33%。此外，CPPC在空气中相当稳定，但在土壤中可比PPC更好地生物降解。这些结果表明，CPPC可广泛应用于涂料、粘合剂、阻隔材料等领域，有望极大促进PPC工业的发展。

Abstract：Poly(propylene carbonate) (PPC), the copolymerization product of carbon dioxide and propylene oxide, was chlorinated for the first time in our laboratory. Nuclear magnetic resonance (NMR) spectroscopy and ion chromatography test showed that chlorine atoms were successfully introduced onto the polymer chains of PPC, and this newborn polymer material was named chlorinated poly(propylene carbonate) (CPPC). It is worth noting that the reaction conditions of the chlorination of PPC were quite mild, which could be easily and simply realized at industrial level. What is more important is that CPPC possessed many more distinguished properties in solubility, wettability, adhesiveness, and gas barrier compared with PPC. For example, the bonding strength of CPPC as thermal adhesive is nearly four times higher than that of PPC for wood, stainless steel and glass. The oxygen permeability coefficient of CPPC exhibits a decrease of 33% compared with that of PPC. Moreover, CPPC is quite stable in air, whereas it could be well biodegraded in soil compared with PPC. These results indicated that CPPC could be widely used in the fields of coating, adhesive, barrier materials and so on, which could greatly promote the development of PPC industry.
