摘要: PSt-PEO嵌段共聚物,由于其PSt链段的亲油性及无定形性,PEO链段亲水性及结晶性所具有的两重性质[1],使得它们在理论研究及实际应用上都具有较大的意义。但对其结晶度及晶粒大小的测定还不曾见报导。

Abstract: The crystallinity and crystal size of different type polystyrene (PST) -polyoxyethy-lene (PEO) block copolymers and the same type block copolymers with different PEO contents have been determined by X-ray diffraction method.It was found that the crystallinity and crystal size increase with the increase of the PEO content and decrease inthe order: BAB>AB>ABA.
