1.Different kind and concentration of synergistic agents were added into multi-component mix-IFR. The sequence of synergistic catalytic flame-retarded effects(an increase in LOI of flame-retarded materials per unit mass of synergitic agent) is as follow: dextrine(DTR)>sodium molybdate(SMD)>cellulose methylate(CM)>ZnO>boracic acid(BA).
