Influência do sulfato de condroitina na formação de filmes isolados de polimetacrilato: avaliação do índice de intumescimento e permeabilidade ao vapor d'água

Abstract: WATER VAPOR. Natural or modified chondroitin sulfate was incorporated in to polymethacrylate to obtain isolated films. The addition of polysaccharide to synthetic polymers occurred at different rates. Isolated films were micro and macroscopically characterized and swelling index and water vapor transmission were determined. Results indicated changed transparency and flexibility, coupled to their dependence on increase in polysaccharide concentration. A similar occurrence was reported in the permeability to wat… Show more

“…These results are similar to the Bunhak et al (2007) who analyzed the WVT of polymethacrylate free films containing the chondroitin sulfate polysaccharide. The authors found that the increase of the polysaccharide contents generated a proportional increase in the rate of WVT.…”
