本研究係以苯乙烯為單體,Living polystyrene (PSlc)為活性高分子型共同安定劑,SDS為界面活性劑之迷你乳液系統,於25 ℃下,改變不同分子量之活性高分子共同安定劑的體積分率,探討迷你乳液之安定性及奧斯瓦老化速率與Lin和Chern 所提出之經驗式的關係。
再者,比較以具有相似分子量的活性聚苯乙烯(PSlc)與非活性聚苯乙烯(PSc)為共同安定劑對迷你乳化的奧斯瓦老化效應之影響。
最後將穩定的迷你乳液送入反應器中反應,藉由改變活性高分子型共同安定劑之分子量(Mn)與體積分率及起始劑(SPS、AIBN)探討反應過程中乳液的成核機制與動力學關係。
The object of this study are use Living Polystyrene as a costabilizer and SDS as a surfactant on styrene miniemulsion system at 25℃ by varies the volume fraction and molecular weight of costabilizer to probe Ostwald ripening effect.
Moreover, Ostwald ripening behavior by using polymeric as a costabilizer have been investigate and develop by Chern. The Kabal’nov equation has been modified to describe regarding the Ostward ripening rate have decrease against with increasing the polymeric costabilizer. Thus the thermodynamic parameter as the Flory-Huhhins interaction paramerter (Χ_(m,p)) was investigated by using the modification of Kabal’nov equation in this miniemulsion system either.
In this study, the minemulsion polymerization technique prepare by Styrene/ Living Polystyrene latexes. The nucleation mechanism and kinetics in the miniemulsion system were investigated by changing different initiators (SPS、AIBN) and molecular weight (Mn) of costabilizer.
