| 摘 要： | 前曾报道羧化度为8～lOmol%的羧化聚苯醚(C-PPO)与PS共混体系具有UCST和LCST共存的特殊相行为1],而羧化度大于11.6mol%时,C-PPO/PS共混体系表现出不相容性2,3]。化学改性PPO可作为PPO与其他聚合物共混的增容剂。本文讨论C-PPO的正十二酯(Lau-CPPO)对C-PPO/PO共混体系混溶性的影响。

| Abstract: | The lauryl ester of carboxylated PPO with 16.0mol% of carboxylation (Lau-CPPO) can be used as a compatilizer for C-PPO/PS blend. The DSC results showed that when Lau-CPPO was more than 30wt%,the system became miscible.TEM microphotographs of C-PPO/PS/Et-CPPO blend showed that the interphase was blurred, the phase permeation was emehanced, and the phase size became smaller with the increase of Lau-CPPO in the blend. |

| Keywords: | carboxylated PPO polystyrene blend lauryl PPO carboxylate compatibility |
