Maleic anhydride grafted trans-1,4-polyisoprene (TPI-g-MAH) was successfully prepared, and characterised through FTIR and the chemical titration method. Furthermore, effect of TPI-g-MAH on the mechanical properties of the glass fibre reinforced nylon 6 was investigated. The results show that TPI-g-MAH can improve the toughness of glass fibre reinforced PA6 composite material, and composite material has excellent comprehensive performance when the content of TPI-g-MAH reaches 4%.
