摘要：

The quasi-static mechanical properties of lamellar block copolymer microstructure in weak segregation are calculated. In analogy with the smectic A liquid crystal phase, the mechanical properties are represented in terms of a layer compressibility and an elastic splay constant. Shifts in the order-disorder transition and metastability limit as well as the decrease in the degree of phase separation due to deformations are also calculated. Several applications of the calculated distortion free energy expression are discussed.
