| Abstract: |
| The rubber crumb modified by heavy oil and styrene copolymer was used to toughen waste PP.The influence of the two monomers mole ratio and their proportion to rubber crumb on the copolymerization and the influence of the proportion of monomers to rubber crumb and the level of modified rubber crumb on the physical properties of PP composite were investigated.The results showed that the polymerization of the residual unreacted monomers was promoted by blending；the impact strength and tensile strength of the composite were respectively 100% and 79.3% higher than those of the waste PP when the mole ratio of heavy oil and styrene was 1，the level of modified rubber crumb was the same as that of monomers，and 20 parts of modified rubber crumb were used in 100 parts of waste PP.The SEM and TEM view on the impact section showed a compatible interface between the modified rubber crumb and the waste PP. |
