| 摘 要： | 采用红外光谱、凝胶渗透色谱等对合成的酚醛缩多元聚醇（PRX）进行结构表征，并研究PRX涂膜的贮存期、物理机械性能、抗化学介质性能和耐热性．结果表明：酚醛树脂中羟甲基与多元聚醇中的羟基发生缩聚反应，形成具有聚醚结构的PRX聚合物．同时，PRX在热固化过程中由于分子链中活泼羟基进一步缩合，产物易交联聚合成膜，该膜具有优异理化性能、耐热性且贮存稳定性较佳．

| Abstract: | The paper concerns the synthesis of the Phenol-aldehyde-polyhydric alcohols co-polymer(PRX) using IR,GPC,etc.The storage time,chemistry resistance,heat resistance and physical-mechanical properties of the coating film of PRX are also investigated.The results of IR and GPC test indicate that the polycondensation between hydroxymethies of PR and hydroxyls of polyhydric alcohols,forms the structure of polyether in co-polymer.then the active hydroxyls of PRX in the heat solidifying process could interact with a... |
