Abstract

Melt blends of polymide 6(PA6) and polypropylene grafted maleic anhydride(PP-g-MA) were prepared to study the influence of chemical reaction between the two polymer components. The tensile, flexural, izod impact, dynamic mechanical properties and phase structure were investigated for this blend system. Tensile strength and modulus of the blends showed synergetic effect upon blending of two polymer components. Flexural properties maintained the value of numerical mean calculated from the weight ratio of two components. Also, notched izod impact strengths showed maximum in th PA6/PP-g-MA 50/50 wt % blend. From the change of tan ${\delta}$ observed, we confirmed the increase of miscibility in this blend system by chemical reaction between PA6 and PP-g-MA. Blends of good impact resistance could be obtained when the PP-g-MA particles of $2{\mu}m$ was dispersed in the PA6 matrix.
