摘　　要：合成并表征了以双金属氧联醇盐为催化剂合成的环氧乙烷与环氧丙烷的无规共聚物及以甲苯二异氰酸酯为偶联荆、聚乙二醇、聚丙二醇及双羟基聚苯乙烯为原料合成的（氧乙烯－氧丙烯－苯乙烯）多嵌段共聚物。用小角Ｘ射线衍射及ＤＳＣ分别研究了两类共聚物及其与ＬｉＣｌＯ＿４络合物的结晶度，还测定了两类络合物的导电率，结果表明，在室温均呈现较高的导电率（１０－４Ｓ／ｃｍ）。Random copolymers of ethylene oxide and propylene oxide were synthesized using bimetallic oxoalkoxide as catalyst and (oxyethylene-oxypropylene-styrene)multiblock copolymers were prepared by coupling poly (ethylene glycol),poly (propylene glycol) and telechelic hydroxyl polystyrene together,using toluene diisocyanate as coupling agent, in order to prepare the solid polymer electrolytes with high room temperature conductivity. The two kinds of copolymers were characterized with IR and 1H NMR and complexed with LiClO4. The crystallinity of copolymers and their complexes was studied using WAXD and DSC. The complexes of beth kinds of copolymero show higher room temperature conductivity of 10￣(-4) S/cm. The relationship between the room temperature conductivity,crystallinity and composition of each kind of copolymres was discussed.
