https://doi.org/10.1007/978-2-8178-0297-8, the cylinder and the lamella, were identified from small angle x-ray data. More recently, Kovacs et al (7–9) have studied single crystals of PS-PEO AB type blocks and have shown that PEO crystallizes with little interference from the glass forming PS in dilute solution experiments. They also indic

Studies on Domain Formation Mechanism of A-B Type Block Copolymer from its Solution,ter of the dynamic modulus-temperature relation including the high-elasticity, have been explained in terms of a two- phase structure originating from the microphase separation of the block segments into respective domains (1–12).

https://doi.org/10.1007/BFb0028912se linear polymers show similar behavior to that of crosslinked networks, presumably due to the fact that the polystyrene end blocks aggregate into “domains”, because of their incompatibility with the polydiene, and these glassy domains can act as “network” junctions at ambient temperatures.
