摘要
将聚(苯乙烯-丙烯酸)(PSAA)(MW=3500)与氯化铜在异丙醇溶液中反应得到一种配位聚合物膜———聚(苯乙烯-丙烯酸)-氯化铜(PSAA-Cu(Ⅱ)).以ESR,FT-IR,XPS,电导率,元素分析及DMTA等方法对此配合物膜进行表征,确定了组成与结构.结果表明,配位聚合物的中心离子Cu2+与二个链节单元上的羧基发生配位,从而引起进一步的交联作用,导致玻璃化转变温度和耐热性能的提高.
The film of copper-poly(styrene-acrylic acid)coordinated polymer (PSAA-Cu(Ⅱ))was obtained through the reaction of copolymer of styrene and acrylic acid (MW=3 000)with copper chloride isopropyl alcohol solution.The PSAA-Cu(Ⅱ) film was characterized by ESR spectroscopy,FT-IR Spectrometry,XPS,specific conductivity,Elemental analysis and DMTA.Its composition and surface structure were determined.Experimental resulits show that each copper ion of PSAA-Cu(Ⅱ) is coordinated with carboxyl from two units,making the coordination polymer cross-link further.The result of DMTA shows that the title polymer has a higher glass transition temperature and thermal resistance.
