【摘要】 将丙烯酸/丙烯酰胺二元共聚物与聚乙烯醇共混后经热交联处理得到吸水性较好的聚丙烯酸/聚乙烯醇共混树脂,利用傅立叶红外光透射谱图(FT IR)、热重谱图(TG DTA)和动态力学分析温度谱图(DMA)详细分析了树脂的结构和热性能.结果表明,共混物大分子间形成了有效的化学交联点且二元共聚物与聚乙烯醇间存在相互作用.更多还原

【Abstract】 The crosslinked polyblends of crosslinked polyacrylate acid (PAA) and poly vinyl alcohol (PVA) are capable of absorbing many times weight water. FT-IR, TG-DTA and DMA spectra are introduced to analyze the polyblends structure. The results show that there are lots of chemical crosslinking points in the blend after being crosslinked and macromolecules of PAA and PVA are interacting each other.更多还原
