| Abstract: |
| The copolymerization of EPDM-g-SAN usingn-heptane/toluene as solvent was investigated.The optimized reaction conditions from the test were as follows：the mass ratio of styrene monomer/acrylonitrile monomer 3/1，the mass ratio of EPDM/monomers 45/55，the concentration of initiator BPO 3.38×10-3mol·L-1，the volume ratio of n-heptane/toluene 60/40，the reaction temperature 80 ℃ and the reaction time 20 h.Under these conditions，the conversion，graft yield and graft efficiency of reaction monomers were 75%，33% and 36% respectively.It was confirmed by IRS that the branched chain of SAN was grafted on the back bone of EPDM. |
