수용성 Polymer-metal Complex의 형성과 중합 개시제로서의 활용성에 관한 연구(Ⅱ) = The Formation of Water-Soluble PMA and PAAm-Cu(Ⅱ) Complexes and their Application as Initiator

다국어 초록 (Multilingual Abstract)

The optimum conditions for the formation of PAAm-Cu(Ⅱ) and PMA-Cu(Ⅱ) complexes have been determined through thermal analyzing and scanning electron microscope measurements. In addition, it was found that they can be used as an initiator for methylmethacrylate(MMA) and styrene vinyl type monomers and as a catalyst of alkylation.
Water-soluble PMA-Cu(Ⅱ) complex had the first endothermic reaction around 380℃ and endothermic reaction around 400℃, respectively and then the secondary exothermic reaction only was observed around 450℃. As pH is increased the formation of water soluble PMA-Cu(II) complex has become more compact.
It was also observed that the function as catalyst of alkylation and an initiator of the water-soluble PMA-Cu(Ⅱ) complex is very active at around pH7 and the complex can polymerize MMA and styrene monomer up to 9% and 8% conversion.
These results can explain the fact that formed complex can be used as good initiator and catalyst.
