摘要

The article describes the mechanical properties of a propylene-ethylene block copolymer (Co-PP) used as a matrix with acrylic acid (AA) and strengthened with glass fiber. Isotactic polypropylene (i-PP) is also used as a matrix to compare with the results obtained from the Co-PP grafting. Experimental results indicate that AA grafting improves the interfacial adhesion between the matrices and glass fiber. AA. grafting also enhances the mechanical properties of glass fiber-reinforced polypropylene (FRPP). A quantitative titration is performed to analyze the grafting ratio and grafting efficiency. In addition, the specimens are injection-molded to investigate the mechanical properties and morphologies. In addition, the effects on the matrix structure, attributed to the grafting and blending of the glass fiber, are also investigated. (C) 1998 John Wiley & Sons, Inc. [References: 24]
