Effect of Filler on the Drawability and Molecular Orientation of Drawn Polypropylene Filled with Metallic Glass Particles

Polypropylene 납유리 입자복합계에 있어서 정신에 의한 분자배향에 대한 Filler의 효과

The effect of filler on the draw ratios and chain molecular orientation of anisotropic polypropylene/Pb-glass particles composite material prepared by uniaxial drawing were measured. And the draw ratio of polymer matrix in drawn composite system was calculated by the simple model. From the calculated value, the amount of bound polymer can be found. Thus, it is concluded that decrease of average chain molecular orientation is partly due to the bound polymer which is formed around the filler surface and partly due to the hindrance effect of filler particles on the molecular orientation.
