초록

전분의 친수성 및 반응성을 조절하기 위하여 propylene oxide, 1,2-epoxvbutane, glycidy1 methacrylate, maleic anhydride, caprolactone 등을 반응시켰으며 건조되지 않은 전분을 사용할 경우 propylene oxide, maleic anhydride 외에는 반응 수율이 아주 낮아지는 것이 관찰되었다. 이렇제 개질된 전분을 스티렌과 반응시켜 그라프트 공중합물로 전환하였으며 여러가지 중합방법에 대한 그라프트 수율이 비교되었다. 그라프트 중합반응의 경우 용액중합 및 cerium(IV)이온에 의한 중합은 각각 낮은 효율과 수율을 보였다. 현탁중합 방법으로는 전분 입자의 친수성 때문에 폴리스티렌으로 전분을 encapsulation 하기가 어려웠으며, 유화중합이 스티렌을 그라프트 시키기에 제일 적당한 방법임을 알 수 있었다.

The com starch was treated with propylene oxide, 1,2-epoxybutane, glycidyl methacrylate, maleic anhydride, caprolactone, respectively, in order to alter the hydrophilicity and the reactivity of starch. When the starch was not dried, poor reaction was observed except the reaction with propylene oxide or maleic anhydride. The treated starches were grafted with styrene by several different polymerization methods. Solution polymerization and redox polymerization using cerium(IV) ion show poor grafting efficiency and poor yield. Encapsulation of starch with polystyrene by suspension polymerization was difficult due to the hydrophilicity of the starch. Among the examined methods, emulsion polymerization was found to be the suitable way to graft styrene onto starch.
