| 초록 | Collecting refuses in nondegradable bags and burying them in reclamation sites make the ground foundation of the reclamation sites unstable and give rise to the water clogging phenomena causing rain water to overflow leading to contamination of the surrounding river or soil. Due to the excessive price of the biodegradable materials developed so far, compounding of the biodegradable materials with synthetic nondegradable plastics has drawn great interests to bring a solution to the above environmental problems. Poly(ethylene-co-vinyl acetate)(EVA) powders containing 10wt% of vinyl acetate units was saponified in ethanol/KOH solution in a heterogeneous manner. Chemical reaction between hydroxyl group of saponified EVA and carboxyl groups of poly(L-latic acid)(PLLA) was nearly undetectable in EVA/PLLA blend system, and the tensile properties of the blend were not enhanced significantly. However addition of tetrabutyl titanate(TNBT) during the blending procedure improved the tensile properties significantly through an increased interfacial adhesion between the components in the blend system. |
