Gravity dependent heat and mass transfer mechanisms often play important roles in material processing. The usage of high gravity conditions for experiments on crystal growth is known. A new field of applications could be the synthesis of polymers. Gel polymerization displays very high gravitational 1-4 and the final sample structure shows traces of all the gel formation stages. There are two main reasons for that; reaction exothermicity and the appearance of a new more dense phase. If the reaction develops nonuniformly, then the above factors lead to density gradients and to macroscopic flows. Transport phenomena directly influence the resulting gel macrostructure. However, the processes forming macro- and microstructures are interconnected. Thus reciprocal influences exist, since the molecular characteristics determine such macroscopic gel parameters as elasticity, permeability, etc.
