Influences of molecular weight of PVC, contents of DOP and CaCO on expansion factor and cellstructureof theleather were in- 3 vestigated.It is noted that the foaming capacity of the three foaming agents, DDL-105, DDL-107 and AC,corresponds to their decomposition feature respectively. The expansion factor and cell structure be- come ideal when the leather is madeof PVC S 700 and right contents of DOP and CaCO . 3 Key words: poly(vinyl chloride) ; artificial leather; blowing agent , PVC [1] DOP CaCO , 3 ,, , , 1
