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。

METHODS:① Stimulus test: A total of 18 Wistar rats were randomly divided into two groups. Unhairing area sizing 4 mm × 4 mm was selected from bilateral spine. One area was wrapped with hydrogel, and the other area was wrapped with polyurethane membrane.

①刺激实验：选取18只Wistar 大鼠，随机分为2组，在大鼠脊柱两侧各选4 mm×4 mm面积的去毛区，一组使用水凝胶义眼台材料，一组使用静电纺丝法聚氨酯薄膜材料，包扎固定4 h后除去斑贴物，对实验部位的红斑和水肿反应评分。

The reason for the undeserved complications of polyacrylamide hydrogel injection for augmentation mammaplasty is unstandard operation.

出现聚丙烯酰胺水凝胶注射隆乳并发症主要原因是操作不规范引起。

The apparent degree of network chains for the different swollen extent of the same unswollen hydrogel sample increased linearly with the increase of swelling ratio, however, the apparent modulus did not decrease monotonously with the increase of swelling ratio. Furthermore, the dependence of apparent degree of network chains on swelling ratio had nothing to do with the swelling agent. The above results reflected the changes of entanglement and the contribution of entanglement under different swelling ratio, and the results could be explained with the theory of Flory-Erman's constrained junction model and LangleyGraessley relation.

发现同一水凝胶样品的不同溶胀程度试样经应力应变测试得出的表观网链密度随体积溶胀率的增加而线性增加，等效模量并不随溶胀程度的增加而单调减小，而表观网链密度的溶胀程度依赖性与所选用的溶胀剂无关，该结果反映了不同溶胀程度下缠结的变化及缠结对弹性的不同贡献，并可由Flory-Erman的constrained junction模型及Langley-Graessley公式得到解释。

MATERIALS: Ethylene glycol methacrylate compound with methyl methacrylate was mixed with NaCl solution to obtain porous hydrogel orbital implant; polyurethane membrane was established using electrospinning method. A volume fraction of 75% ethanol was used to make homologous sclera wrappage.

材料：用甲基丙烯酸-β-羟乙酯和甲基丙烯酸甲酯的聚合物单体加入NaCl成孔剂制备多孔水凝胶义眼台；静电纺丝法制备聚氨酯包裹膜；体积分数为75%乙醇浸泡制备同种异体巩膜包裹物。

The effects of the crosslinking agent concentration, the neutralization degree of monomer and the composition of the copolymerized monomer on the hydrogel strength were investigated.

结果表明，树脂的交联密度是影响凝胶强度的最主要因素；而树脂的饱和吸水性对凝胶强度有一定的抑制作用。

Was widely used in medical treatment,such as bone cement,dental filler,cornea contact hydrogel, tissue adhesive ,burn dressing and inserting granular embolus.

由于这种高分子材料具有组织相容性好，机械强度高，无毒和室温固化等性能，可在医疗方面广泛应用，如用作骨水泥、齿科充填材料、角膜接触镜、组织粘合剂、烧伤敷料和介入栓塞剂等。

Nanoparticles encapsulating PPA HCl were prepared using the solid jelly pulverization technique. The size of the PPA HCl - hydrogel nanoparticles was assessed using a LS particle size analyzer and scanning electron microscopy. The rheological properties of suspensions are characterized by Cone and Plate Viscometer. In addition, any drug-polymer interactions were assessed using a differential scanning calorimeter.
