Abstract

"COPOLìMERO DE ESTIRENO E DIVINILBENZENO FUNCIONALIZADO COM ELEVADO GRAU DE GRUPAMENTOS AMINO-METìLICOS <B>(EPM-1)<D> E SUA UTILIZAçãO COMO NOVO TIPO DE RESINA TROCADORA ANIÈNICA" Resinas contendo matrizes apolares do tipo estireno-divinilbenzeno podem se tomar solvatáveis em meio aquoso, dependendo da quantidade de grupamentos amínicos positivos incorporados em sua estrutura. Ensaios com uma resina contendo grupamentos aminometilicos e denominada amino-metil-resina, contendo 4,9 mmol/g de teor amínico, aqui denominada EPM-1, mostraram que ela se solvata bem em meio de solvente orgânico polar e mesmo em água. Baseado em uma estratégia especial desenvolvida para se estimar pKa de grupos ionizáveis de resinas, foi encontrado valor ao redor de 5,5 para o pKa do amino grupo desta resina. Como modelo de composto aniónico para os ensaios cromatográficos com a EPM-1, fragmentos peptídicos com diferentes cargas negativas foram sintetizados e testados em purificação em coluna, demonstrando que este polímero pode ser considerado uma resina alternativa do tipo trocadora aniónica e o seu emprego pode ser estendido para a purificação de outros tipos de compostos com cargas negativas. Além do mais, por possuir amino grupos primários, facilmente deriváveis em sua estrutura, esta resina pode se tornar também precursora de outras resinas com diferentes potencialidades cromatográficas. O mesmo pode ocorrer caso de altere por exemplo, o grau de intercruzamento de divinilbenzeno deste copolímero, induzindo mudanças em suas características de solvatação, porosidade, etc, afetando portanto a natureza de seu emprego como matriz polimérica."COPYLYMEN OF STYLENE AND DIVINYLBENZENE FUNCTIONED WITH HIGH DEGREE OF AMINO-METHYLIC GROUPS <B> (EPM-1) <D> AND ITS USE AS A NEW TYPE OF ANTI-EXCHANGE RESIN" Resins containing non-solvable styrene-type solvents, in aqueous medium, depending on the amount of positive amino groups incorporated in its structure. Tests with a resin containing aminomethyl groups and called amino-methyl-resin, containing 4.9 mmol / g of amine content, here called EPM-1, showed that it solvates well in polar organic solvent and even in water. Based on a special strategy developed to estimate pKa of ionizable groups of resins, a value of around 5.5 was found for the pKa of the amino group of this resin. As a model of anionic compound for chromatographic assays with EPM-1, peptide fragments with different negative charges were synthesized and tested in column purification, demonstrating that this polymer can be considered an alternative resin of the anion exchanger type and its use can be extended to the purification of other types of compounds with negative charges. Furthermore, because it has primary amino groups, easily derivable in its structure, this resin can also become a precursor to other resins with different chromatographic potentials. The same can occur in case of alteration, for example, the degree of intercrossing of divinylbenzene of this copolymer, inducing changes in its characteristics of solvation, porosity, etc., thus affecting the nature of its use as a polymeric matrix.
