实验室在环氧大豆油树脂的高性能与热塑性化研究取得重要进展
环氧大豆油作为一种可再生的生物质资源,在高分子材料领域获得了重要应用,不仅广泛用作聚氯乙烯等的环保增塑剂,而且可以与多元酸固化,制备生物基热固性树脂。然而这类热固性树脂力学性能极差,断裂强度通常低于1MPa,断裂伸长率不足30%,用途极为有限。
实验室最近几年在环氧大豆油树脂高性能化方面开展了研究工作,首先利用生物基二元酸与环氧大豆油固化,制备了全生物基环氧大豆油树脂,研究了环氧大豆油树脂固化的动力...

魏人建博士关于DMCC催化环氧单体-CO2共聚结构效应的文章发表于Macromolecules上
In this study, we describe the substituent effect of epoxides on CO2/
epoxide copolymerization catalyzed by a nanosized zinc?cobalt(III) double metal
cyanide complex [Zn?Co(III) DMCC]. The Zn?Co(III) DMCC catalyzed the
copolymerization of CO2 with 11 epoxides with alkyl or aryl groups at 50?60 °C
within 15 h. The reaction afforded various CO2/epoxide copolymers with high epoxide
conversion ...

硕士生张滢滢等关于长烷基链环氧单体与CO2共聚及与“极性”环氧单体三元共聚的研究发表于JPSA上,并选为内封面
The alternating copolymerization of CO2 with the terminated epoxides anchoring long alkyl groups is rarely reported because of their low reactivity and polycarbonate selectivity. This work describes a well-controlled solvent-free copolymerization of CO2 with 1,2-epoxydodecane (EDD) with a long electron-donating alkyl group via the catalysis of Zn-Co(III) double metal cyanide complex ca...
