本研究以團聯共聚物polystyrene-block-poly(ethylene oxide) (PS-b-PEO)與sodium dodecyl sulfate (SDS)以及均聚物poly(acrylic acid) (h-PAA)進行混摻，觀察其相行為及結晶行為。
對稱型PS-b-PEO與SDS混摻時，PEO與SDS形成complex但不影響PS-b-PEO之層狀結構。添加30 wt% SDS時，較多SDS進入PEO domain中，使其domain size變大，此外，SDS與PEO形成complex會破壞PEO之對稱結構，使PEO不易結晶，因此PS-b-PEO之半結晶時間增加、結晶度與結晶溫度則下降，結晶速率也明顯變慢。此外，SDS與PEO鏈段相容，與PS鏈段則不相容，SDS與PS鏈段之間的排斥力會干擾PS-b-PEO之層狀結構，使PS-b-PEO有序-無序轉換溫度下降，較易成為無序結構。
將PS-b-PEO與不同分子量之h-PAA進行摻合，由於PEO與PAA可以形成氫鍵，因此h-PAA進入PEO domain中，使其domain尺寸變大，但不改變層狀結構。當摻入10 wt% 分子量較小的h-PAA時，其結晶溫度、結晶層厚度、結晶度、結晶速率與晶粒大小均減小。混摻20 wt%的h-PAA時，與PEO鏈段形成氫鍵的PAA阻礙了PEO的結晶，造成混摻分子量較小的h-PAA時，產生冷結晶現象，混摻分子量較大的h-PAA時PEO無結晶產生。

We studied the nonisothermal crystallization and order-disorder transition of polystyrene-block-poly(ethylene oxide) (PS-b-PEO)/sodium dodecyl sulfate (SDS) blends and PS-b-PEO/poly(acrylic acid) (h-PAA) blends.
The PS-b-PEO/SDS blends exhibited a lamellae structure. Because the PEO block and SDS were miscible, whereas the PS block and SDS were immiscible, SDS molecules were segregated into the PEO microdomains. The PEO and SDS complex disturbed the symmetry structure of PEO, thereby prohibiting the PEO crystallization. This resulted in the decrease of crystallization temperature, onset crystallization temperature, and degree of crystallinity. When 30 wt% SDS was added in PEO, the half crystallization time was prolonged considerably. The formation of PEO/SDS complex also decreased the order-disorder transition temperature because of the repulsion between SDS and PS chains.
In PS-b-PEO/h-PAA blends, the addition of h-PAA in PS-b-PEO decreased the crystal thickness, grain size, crystallization temperature, onset crystallization temperature, and degree of crystallinity. This was attributed to the formation of hydrogen bonding between PEO and PAA that disturbed the PEO crystallization. Furthermore, h-PAA was localized in the PEO domains, which increased the domain size without changing the microstructure of PS-b-PEO. Such effects were more pronounced when small molecular weight of h-PAA was blended. Cold crystallization occurred when 20 wt% small molecular weight h-PAA was added in PS-b-PEO, whereas that with a high molecular weight of h-PAA, the hydrogen bonding between PEO and PAA prevented PEO from crystallization, and PEO crystallization did not occur.
