A Study on Morpolgy and Impact Property in the blends of Styrene-Butadien Block Copolymer and Styrene-Methylmethacrylate Copolymers

초록

Ductile matrix/Brittle particle system의 한 유형으로서 styrene-butadien block copolymer(SBS)를 ductile matrix로 고정하고 brittle particle로써 존재하는 일련의 styrene-methyl-methacrylate copolymer(SMMA)와의 블렌드에 대하여 SMMA중 MMA함량이 변함에 따른 구성 성분간의 계면접착 정도, 형태학, 그리고 블렌드의 충격강도의 변화에 대하여 고찰하였다. 적정수준의 MMA 및 SBS 함량에서 몇가지 블렌드들은 충격강도에 있어서 상당한 synergism이 있음을 확인하였으며 주어진 system에 대한 강인화 조건에 대하여 구성성분간의 계면접착 정도 및 brittle polymer의 particle size를 연관지어 설명하였다.

A study on polymer blends containing particles of brittle polymers dispersed in the matrix of ductile polymer has been undertaken. A series of styrene-methylmethacrylate(SMMA) copolymers as brittle polymers having various MMA contents of 0%(polystyrene) to 100%(polymethylmethacrylate) have been incorporated into block copolymer of styrene and butadiens(SBS) as a fixed ductile matrix. The major focus has made the effect of the composition of SMMA copolymer on blend toughness, interfacial adhesion and morphology. A profound synergitic toughening was observed for selected pairs of the blends containing appropriate levels of SBS and MMA contents in SMMA. Issues relating to the requirement for effective toughening are discussed in terms of interfacial adhesion and optimum particle size of the brittle polymers.
