초록

Polar amino groups of the waste SS(silk-sericin) and hydroxyl groups of the chitosan were modified by isocyanate compound of MOI[2-(methacryloyloxy)ethyl isocyanate] and MAC(methacryloyl chloride), respectively. When the MOISS(MOI-modified silk sericin)/MACS(MAC-modified chitosan) blend system was pressed with high temper ature, vinyl groups in the MOI or MAC were polymerized and then the flexible and transparent films were obtained. By the polymerization of vinyl groups in the MOISS/MACS blend system, tensile moduli and strengths of the MOISS/MACS blend films exhibited highest level in blend ratio of MOISS/MACS=20/80. The MOISS/MACS blend films exhibited similar solubility to the distilled water $(80^{\circ}C)$ regardless of the MOISS/MACS blend ratios and also higher swell ratios to the distilled water(room temperature) as the MACS contents increased. With increasing MACS content, BOD(biochemical oxygen demand)/TOD(theoretical oxygen demand) decreased.
