Resumo
In this study the optimum conditions of crosslinking of three varieties of the synthetic copolymer (copolymer of methyl vinyl ether and maleic anhydride) and triethanol amine have settled down with a view to their potential use in systems of active substances delivery. The behaviour has been characterized thermally of different mixtures between the copolymer and the crosslinking agent over the study of different parameters (molar mass, temperature, time of incubation and concentration of crosslinking agent). The results show a very similar behaviour among the three varieties studied of the copolymer. The crosslinking of the copolymer takes place in a quick way under soft conditions of temperature, therefore this system presents certain advantages when using it like support for unstable or thermolabiles active substances.
