A shape memory polymer is disclosed. The shape memory polymer is a random polyester copolymer formed by performing an esterification and a polycondensation using at least one aromatic diacid, at least one linear aliphatic diacid or imide-containing diacid and at least one linear aliphatic diol. The shape memory polymer has a viscosity [η] of 0.3-0.8dL/g, a glass transient temperature Tg of 30 DEG C to 100 DEG C, a melting point Tm of 170 DEG C to 250 DEG C and a shape recovery rate of 60% to 90%.
