| 摘 要： | 经共聚改性的聚苯乙烯PS(OH)与聚甲基丙烯酸丁酯PBMA形成的互溶体系具有LCST行为。由于体系的玻璃化温度较高。分相温度与玻璃化温度接近。使分相时的浊点温度受升温速率影响很大,以致浊点曲线与相平衡曲线有一定的差距。本文以邻苯二甲酸二丁酯DBP为增塑剂加入PS(OH)/PBMA共混体系中,在一定的升温速率下测浊点温度,并对增塑剂作零浓度的外推,由此得到的浊点曲线与相平衡曲线完全一致。证实了增塑剂法的可靠性。加入增塑剂后浊点温度随升温速率变化平缓,更接近相平衡点,显示了增塑剂法的有效性。

| Abstract: | Polyblend PS(OH)/PBMA has a LCST bahavior. The cloud points are strongly dependent on heating rate and the difference between cloud point curve and binodalcurve ia apparently. By adding the plasticizer DBP into the polyblend, the dependence of cloud point on heating rate is changed. The accuracy and the effectiveness of adding plasticizer were proved in this paper. |
