本文首次报道了聚（甘油-癸二酸酯）（PGS）弹性体具有良好的形状记忆性能。结果表明，PGS的交联三维网络结构作为固定相，PGS的非晶相作为可逆相是PGS具有形状记忆行为的两个必要条件。形状记忆效应的响应温度与PGS的玻璃化转变温度有关。所研制的PGS聚合物具有良好的形状记忆效应，其形状记忆率可达99.5%以上。(C)2007 Elsevier B. V.保留所有权利。
In the present work, we report the excellent shape-memory behavior of Poly (glycerol-sebaeate) (PGS) elastomer for the first time. It is found that the crosslinked, three-dimensional networks of the PGS acting as fixed phase and the amorphous phase of the PGS acting as reversible phase are the two necessary conditions for PGS with shape memory behavior. The response temperature of shape memory is dependent on the glass transition temperature of PGS. The PGS polymer developed has an excellent shape-memory effect, having a shape-memory ratio of above 99.5%. (C) 2007 Elsevier B.V. All rights reserved.
