초록

PMMA와 본질적으로 비상용성인 PB에 MMA를 그라프트 중합시켜서 이를 PMMA와 블렌드하여 그라프트율 변화에 따른 내충격성, 인장강도, haze 변화 및 상용성변화를 SEM, DSC, Instrone 등을 통하여 관찰하였다. Poly(butadlene-g-MMA)의 그라프트율이 증가함에 따라서, MMA 그라프트로 인한 PMMA와의 상용성의 증가에 의하여 PMMA-poly(butadlene-g-MMA) 블렌드의 인장강도, 내충격성 및 투명성 등이 그라프트하지 않은 PB-PMMA 블렌드에 비하여 향상되는 결과를 나타내었다. 반면에, 투명성은 PMMA 단독수지에 비해서는 다소 떨어지는 결과를 나타내었다.

Poly(butadiene-g-MMA) was synthesized by grafting methyl metharcylate on polybutadiene which is intrinsically incompatible with poly(mothy methacrylate)(PMMA) and this graft copolymer was blended with PMMA. Mechanical properties of PMMA-poly(butadiene-g-MMA) blends and PMMA-polybutadiene blends, such as impact strength, tensile strength and haze were determined. Morphological changes of the blends as a function of graft percentage were observed by scanning electron microscopy. Mechanical properties of PMMA-poly(butadiene-g-MMA) blends were better than PMMA-polybutndiene blends. Especially, mechanical properties of PMMA-poly(butadiene-g-MMA) blends were improved nth increasing graft percentage of MMA.
