"We adopt the mathematical modeling of the morphogenesis of polyolefin particles as the tool for systematic understanding of various morphogenesis scenarios. The porous polymer macroparticle is assumed to consist of a large number of individual micro-elements (grains), i.e., catalyst fragments jacketed in the polymer layer. The rate of the growth of each particular grain depends on the local catalyst concentration and activity and on the local concentration of the monomer. The morphogenesis of polymer particle is governed by the binary and ternary visco-elastic interactions of individual growing micro-elements. These visco-elastic interactions are described by visco-elastic models, such as Maxwell or more general models. Various types of morphologies of polymer particles are obtained when different visco-elastic properties and/or different initial conditions are considered." . "10"^^ .
