Fractional yield and phase separation of ladder-like interpolymer complexation between diblock copolymers

We analyze the fractional yield and the phase separation of the ladder-like interpolymer complexation reaction between two diblock copolymers A1A2 and B1B2 forming a linear triblock copolymer A1DB1, i.e., A 1 A 2 + B 1 B 2 ⇌ A 1 DB 1 . The study is carried out by using the self-consistent field theory coupled with the interpolymer-complexation model of the chemical reactions. The fractional yield of the complexation ( φ 3 / φ ), defined as the …
