| 摘 要： | 研究了聚对苯二甲酸乙二酯(PET)/离子聚合物surlyn体系的反应.由该体系的熔融行为、分子量的测定及红外光谱分析证实:surlyn的侧基—COONa在高温下与PET的酯键反应,会引起PET断链,并生成PET—COONa和PET—R.在更高的温度下,PET—COONa之间的离子端基可相互反应,生成对苯二甲酸钠,并使PET分子链重新连接起来.

| Abstract: | The reaction system ofpoly(ethylene terephthalate)(PET)and surlyn has been studied. The fusion behavior, element analysis and IR analysis show that at high temperature, the pendant sodium carboxylate groups of surlyn react with ester linkages of PET,breaking the chain of PET and creating PET-COONa and PETR. At still higher temperature, the ionic end points of PET-COONa may react with each other, producing sodium ethylene terephthalate and reforming the PET molecular chain. |
