A systematic study has been made on the functions of external Lewis base (Be, methyl-p-toluate, MPT) and internal Lewis base (Bi, ethyl benzoate, EB) for the CW-catalyst system MgCl,/EB/PC/AlEt,/TiCl,-AlEt,/MF'T (PC, p-cresol). Bi is a nonstereoselective modifier. It increases the active site concen
