摘　　要：以聚碳酸亚丙酯 (PPC)和甲苯二异氰酸酯 (TDI)以及官能性的有机硅烷为原料 ,通过聚氨酯预聚体的方法得到了硅烷化的聚碳酸亚丙酯 (SPPC) ,利用有机硅官能团的可水解性 ,可使Silylated poly(propylene carbonate)(SPPC) was prepared by the reaction of an organic silicone reagent KH550 and poly(propylene carbonate(PPC) with isocyanate end groups which were formed by the treatment of PPC with TDI. In the presence of humidity, SPPC can be crosslinked resulting in a solid product, thus can be expected to be applied as a new kind of sealant.
