Styrene‐divinylbenzene copolymers II. Influence of the nature of the diluent on the texture of macroporous copolymers

Macroporous styrene‐divinylbenzene resins are studied using precipitating agents as diluents. A definition of the macroporous domain is given, based on homogeneous properties and structures. The existence of this macroporous domain is proved to be a general feature of the macroporous resins field. The position of this domain is specified for 4 different diluents. The evolution of the texture of the resins, according to their position inside or outside the macroporous domain is analyzed and discussed.
