  1. In the work, it is founded to study the thermal degradation of the polymer by study the change of toque of micro twin screw extruder

    在本論文工作中，建立了通過微型雙螺桿扭矩變化來研究聚合物的熱降解情況的方法。
  2. Increasing ultrasound intensity in the range of cavitation threshold and cavitation peak value, decreasing monomer concentration and increasing the temperature make the induction period shorter. under optimized reaction conditions, the conversion of ba can reach 90 % in 11 min at high n2 flow rate the viscosity average molecular weight of the obtained pba reaches 5. 24 106. the molecular weight of pba varies with ultrasonic irradiation time, indicating that the ultrasonic induced emulsion polymerization is dynamic and quite complicated, polymerization of monomer as well as degradation of polymer occurs concomitantly

    一、實現了無常規化學引發劑存在下的超聲輻照引發丙烯酸正丁酯（ ba ）間歇乳液聚合，制備了pba納米粒子，在11min內轉化率達到90 ，分子量達5 . 24 10 ~ 6 ，隨反應時間的延長而降低，表明超聲輻照引發乳液聚合是一個動態的復雜過程，單體的聚合和聚合物的降解同時發生。
  3. Standard test method for in vitro degradation testing of hydrolytically degradable polymer resins and fabricated forms for surgical implants

    外科植入物用水解可降解聚酯樹脂和人造支架模型的體外降解試驗的標準試驗方法
  4. Controlling the cp species, content, polymer concentration and solvent scaffolds of different pore structure and degradation rate were achieved

    復合后材料的力學性能較純plla支架有所提高，並表現出較好的生物活性。
