整个过程分为两步，首先在水溶液中，通过RAFT控制得到亲水性单体丙烯酰胺的均聚物；然后以得到的均聚物作为水溶性的大分子链转移剂，在水相中条件下参与亲油性单体苯乙烯无皂乳液聚合。

A three-unite hydrogel that had a thermoresponsive shape memory was prepared by copolymerizing a hydrophobic monomer n-stearyl acrylate with n- undecylenic acid and acrylamide,and its structure and properties were studied by X-ray diffraction,DSC and DMA.

选用疏水性单体丙烯酸十八酯和十一烯酸以及亲水性单体丙烯酰胺制备了三元共聚凝胶P(SA-co-AM-co-HA)，通过X射线衍射、DSC、DMA等对三元凝胶的结构和性能进行了研究，发现三元凝胶形成了有序排列，这种有序排列会随着温度的变化发生可逆转变，从而使凝胶显示较好的形状记忆特性。

The morphology of the mineral dependents on the solution characteristics. The main component of mineral was hydroxyapatite containing a little of CO32- group which the Ca/P ratio is 1.53, similar to the major mineral component of bone tissue. The porosities of the mineralized and unmineralized 3-D porous PLGA were (84.86±8.52)% and(79.70±7.70)% respectively. The biomechanical strength was 0.784±0.156 N/mm2 in unmineralized PLGA and 0.858±0.145N/mm2 in mineralized PLGA.

结果：PLGA经碱性溶液水解处理后表面亲水性明显增强，在0.5倍SBF中仅有少量矿物沉积，在SBF及1.5倍SBF中矿化后表面可以形成明显的矿化物；矿化物的形态与矿化液的浓度有关；矿化物主要成分为羟基磷灰石，含有碳酸根成分，钙磷比为1.53，类似于人骨无机质。
