摘要
It is presented that cocrystallization leading to a solid solution occurs over a broad range of under-cooling in lamellae-forming blends of a nearly symmetric C-b-A with an asymmetric counterpart, while the corresponding homopolymer blends with similar molecular weight and composition exhibit phase-segregated crystallization. Cocrystallization in lamellae-forming blends are driven thermodynamically by the tendency of the short and long PB blocks to remain intimately mixed. The cocrystallization presents a scenario where a kinetics-dominated process found in homopolymer crystallization possibly turns into a thermodynamically favoured process in the C-b-A systems. Chain folding during crystallization in homopolymers is a kinetically driven phenomenon.Cocrystallization Behavior in Binary Blend of Crystalline−Amorphous Diblock Copolymers (PDF Download Available).
