AbstractA model series of ordering of submicroscopic spherical particles forming the basic structure of macroporous copolymers is suggested by analogy with elementary crystallographic lattices. This series with various porosity (p=25.95‐78.53%) allows not only the calculation of the mean radius of submicroscopic particles, but also a better choice of the coefficient used in calculating the mean pore radius from specific pore volumes and specific surfaces. A general method of calculation of the mean particle radius and of the mean pore radius for macroporous copolymers is also proposed, and a comparison with real systems is mad
