AB type PSt-PEO block copolymers were successfully synthesized using a-pheny-lethyl potassium as initiator in toluene
whereas ABA type PSt-PEO block copolymer were prepared by coupling reaction of TDI with hydroxyl terminated AB type PSt-PEO block copolymers. Both AB and ABA types block copolymers of PSt-PEO were characterized by NME
IK
UV
DSC and their bulk properties investigated by X-ray dif-fraction polarization microscopy and DSC.
