Novel scheme for graphical representation of mean-field interaction parameters in statistical copolymer blends — •D. W. Schubert — GKSS Research Centre, Max-Planck-Straße, D-21502 Geesthacht (Germany)

A novel scheme for graphical representation of the interaction parameter for binary blends consisting of two different statistical copolymers P(A_xB_1−x) and P(C_yD_1−y) is presented. The corresponding abstract parabolic equation, describing the interaction parameter as a function of x and y thus receives a pictorial meaning. The scheme is built by a pyramid shaped body where the corners represent the pure copolymer components A, B, C and D. Distances mirror the square root of corresponding interaction parameters. Copolymers are represented by positions on the respective edges depending on compositions.
