摘要：

Microphase separation of ABA triblock copolymers involves bridging of A domains by B blocks. Consequently, the resulting mesophases can form gels when swollen by selective solvents. These <<mesogels>> are characterized by anisotropically distributed junctions of high functionality. The swelling equilibrium of mesogels is characterized by distinctive c* theorems. The elastic response of mesogels exhibits novel features, among them asymmetry of compression and stretching and nonaffine character.
