Objective To synthesize copolymers composed of polyacrylic acid and poloxamer 407, and investigate its thermo -sensitive gelling properties in situ.

目的制备丙烯酸和泊洛沙姆407构成的共聚物，研究其温度敏感的原位胶凝性质。

Factors such as EC, HPC and poloxamer were found to have significant effects on drug release from the SR tablets and no interactions were observed between these three factors.

结果表明，EC、HPC和泊洛沙姆等因素对药物释放有显著影响，这3种因素间不存在相互作用。

The herbal extraction was separated and added into the oil phase and water phase independently, and the emulsion was prepared using soybean phospholipids and poloxamer as the emulsifying agent.

方法将冰片直接溶入油相，对提取液进行油水分离，分别加入油相和水相，以磷脂和泊洛沙姆为乳化剂制成乳剂。
