Schubert plot

Schubert plot for a homopolymer-copolymer mixture

The Schubert plot according to Dirk W. Schubert is a graphic scheme for the representation of interaction parameters in copolymer mixtures (calculated according to ten Brinke).

Simplest example: homopolymer / random copolymer

The homopolymers consisting of the monomers A, B and C are arranged as a triangle, with the distances corresponding to the square roots of the corresponding interaction parameters. The position of the copolymer is given on the connecting line between A and B by the proportion of the B component in the copolymer. The distance between C and the copolymer then corresponds to the square root of the interaction parameter for the homopolymer-copolymer mixture. The height of the triangle indicates a corresponding possible minimum value for this interaction parameter. ${\ displaystyle x}$ ${\ displaystyle s}$ ${\ displaystyle h}$
