羧化聚苯醚/聚(苯乙烯-乙烯吡啶)共混相容性

摘要/Abstract

摘要： 用DSC、DMA研究了羧化聚苯醚(CPPO)/聚(苯乙烯-乙烯吡啶)(PSVP)共混体系的相容性,结果表明,与CPPO/PS体系相比,乙烯吡啶基的引入大大提高了共混相容性。这主要是由于CPPO中的羧基与PSVP中的吡啶基之间通过质子转移形成的正负离子间的相互作用,推动了两组分分子的均匀混合。

Abstract: In the paper the miscibility of carboxylated poly(phenylene oxide)(CPPO)/poly(styrene-co-4-vinylpyridine)(PSVP)blends was investigated by DSC and DMA. It was found that the CPPO/PSVP blends possessed relatively good miscibility compared with CPPO/PS, and this was attributed to the ion ion interactions resulted from the proton transfer between the carboxylic groups of CPPO and the pyridine groups of PSVP.

Key words: carboxylated poly(phenylene oxide), poly(styrene-vinylpyridine), miscibility
