本实验室首次对二氧化碳和环氧丙烷的共聚产物聚碳酸亚丙酯（PPC）进行氯化。核磁共振（NMR）光谱和离子色谱测试表明氯原子成功引入到PPC的聚合物链上。我们将这种新生的聚合物材料命名为氯化聚碳酸丙烯酯（CPPC）。值得注意的是，PPC的氯化反应条件相当温和，可以在工业水平上轻松实现。更重要的是，与PPC相比，CPPC在溶解性、润湿性、粘合性、阻气性等方面具有许多优异的性能。例如，CPPC作为热粘合剂对木材、不锈钢和玻璃的粘合强度比PPC高近四倍。 CPPC的透氧系数比PPC降低了33%。此外，CPPC在空气中相当稳定，而与PPC相比，在土壤中可以很好地生物降解。这些结果表明CPPC可广泛应用于涂料、胶粘剂、阻隔材料等领域，可极大促进PPC行业的发展。
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. We named this newborn polymer material as 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.
