摘　　要：比较了以甲基丙烯酸甲酯 ( MMA)和苯乙烯 ( St)为稀释剂制备的丁羟氨酯丙烯酸树脂固化物的性能与结构。MMA作为稀释剂的体系有更高的强度 ;DSC表明前一体系有更高且更宽的玻璃化转变温度 ;The mechanical properties of cured HTPB polyurethane acrylate diluted by MMA are compared with those by styrene. With MMA as diluent, UAR shows much higher strength and DSC shows that higher and wider glass transition can be observed in the system. SEM study also indicates that phase separation is much stronger in the UAR diluted by MMA.
