Comb Copolymer Brush with Chemically Different Side Chains

Comb Copolymer Brush with Chemically Different Side Chains

An investigation of side chain microphase separation within a single comb copolymer molecule containing chemically different A and B side chains has been carried out. Expressions for the transition point in a good ( ∼ N -3/8), marginal ( ∼ N -1/2), θ ( ∼ N -2/3), and poor ( ∼ N -1) solvent are deriv...

description An investigation of side chain microphase separation within a single comb copolymer molecule containing chemically different A and B side chains has been carried out. Expressions for the transition point in a good ( ∼ N -3/8), marginal ( ∼ N -1/2), θ ( ∼ N -2/3), and poor ( ∼ N -1) solvent are derived both by a mean field calculation and by scaling arguments. Properties of the system below and above the transition point are described. Some unusual “bowlike” conformations are predicted for a single molecule in the microphase separated state in a good solvent.
