Avaliação da porosidade em polímeros monolíticos de metacrilato de metila e divinilbenzeno (MMA-DVB)

Resumo

Monolithic polymers are a class of materials that has grown rapidly in recent years. Porosity these materials is determined by type of inert diluent and degree of dilution. Thus, the present work used solvating and non-solvating diluents for the polymer chains, as well as two degrees of dilution, to produce monolithic polymers of MMA-DVB, with different surface areas, morphological characteristics and porosities. The non-solvating diluent and higher degree of dilution, yielded polymers with higher surface area and higher volume of pores. The solvating diluent and less degree of dilution, yielded polymers with lower surface area and lower pore volume, showing that both the type of diluent and the degree of dilution are parameters that influence the porosity of these materials.
