ABA triblock copolymer-based model networks in the bulk: Effect of the number of arms on microphase behavior

Karbarz, M.; Stojek, Z.; Patrickios, Costas S. (2005)

The microphase separation behavior in the strong segregation limit of model networks based on cross-linked ABA triblock copolymers in the bulk was investigated by calculating analytically the Gibbs free energies of the ...
