摘　　要：采用糠醇和环氧氯丙烷反应制备了纯度较高的呋喃甲基缩水甘油醚,随后呋喃甲基缩水甘油醚与二氧化碳在稀土三元催化剂Y(CCl3COO)3-甘油-ZnEt2的催化下发生共聚反应,生成侧链为呋喃甲醚侧基的脂肪族聚碳酸酯.共聚物主链结构规整,主要为聚酯结构,数均分子量最高可达13.0×104,共聚物的玻璃化转变温度为-29～-30℃,5wt%起始热分解温度大于231℃.To explore the non-petroleum route for carbon dioxide copolymers, furfuryl glycidyl ether oxirane with 99.7% purity was prepared from furfuryl alcohol and epichlorohydrin employing sodium hydroxide and tert- butylammonium sulfate as catalysts, where furfuryl alcohol was a hydrogenation product of furfural from pentose-rich agricultural residues like rice hulls, bagasse, corn cob, et al., and epichlorohydrin could be produced from glycerine furfuryl glycidyl ether was carried out in a 500 mL autoclave with carbon dioxide pressure of 4 MPa at elevated temperatures, using Y （CCl3 COO）3-glycerine-ZnEt2 coordination catalyst and 1,4-dioxane as solvent. Aliphatic polycarbonate with pendant furfuryl methyl ether was obtained with number average molecular weight as high as 13.0 ×10^4 . The glass transition temperature （ Tg ） of the resultant copolymer was around carbonate） （PPC）,providing possibility for solving the - 30℃ ,which was 65℃ lower than that of poly（propylene brittleness of PPC, and the application window of PPC was with common PPC, this new significant improvement in thermal stability, the onset thermal degradation temperature （ Td ） 231 ℃, approximately 60 ℃ higher than that of PPC. polycarbonate showed of the copolymer was
