Abstract

The morphology of the triblock copolymer gels ABA type, where A constitutes a thermoplastic material (e.g. PS) and B an elastomer (e.g. PB), are presented. The triblock copolymer gels can be described as follows: PS endblocks form spherical domains with small polydispersity of radius in a homogeneous of dissolved midblock and solvent. The conformation of the midblock can be close to that of statistical coil in good solvents or a bit compressed and stretched. These elastic links between the PS domains define the short-range order and through the densepaching principle finally influence the morphology of the gel. The order is liquid-like with a mean interdomain distance that is 2 - 3 times larger than the mean diameter of the domains. The results of stretching experiments are consistent with a model of a polymer network exhibiting local coordination (short-range) order.
