Water-insoluble precipitates, polyelectrolyte complex(PEC) were obtained by mixing the solution of poly(L-lysine)(PLL) and poly(vinyl sulfate). The IR spectroscopic studies showed that the structure of PLL in the complex depended on the degree of sulfation. PLL took random coil conformation in the PLL/PVS-25 complex(25: degree of sulfation in mol-%) and random coil, α-helix and β-structure in the PLL/PVS-30, PLL/PVS-46 and PLL/PVS-95 complexes. The solubilities and the color reaction depended on the degree of sulfation. Highly ordered fibrous structures were observed in the electron micrographs of PLL/PVS-46 and PLL/PVS-95 complexes. It is possible that certain stereospecific interaction between two polymers is the cause for the formation of the fibrous structures.

Poly(L-Iysine) (PLL)과 술폰화도가 25, 30, 41, 95%인 Poly(vinyl sulfate)(PVS)와 고분자전해질복합체의 고체구조와 물성을 검토하였다. PLL과 PVS에서 물에 녹지 않는 고분자전해질복합체가 합성되었는데 PLL/PVS-25인 경우의 PLL의 고체구조는 주로 random coil을 PLL/PVS-30, PLL/PVS-41, PLL/PVS-95인 경우에는 α-helix, β-structure, random coil의 구조를 나타내었다. PLL/PVS 복합체의 용해도와 정색 반응은 황산화도에 의존하고 있었고 물에 의한 팽윤성은 없었다. PLL,/PVS-95 복합체와 PLL/PVS-46 복합체의 형성시 입체특이적인 상호작용으로 양고분자 사이에 련포민 정전적 상호작용을 띈 미세조직이 확연하게 나타나는 것이 morphology에서 관찰되었다.
