GUERRERO, R. F. E; TALAVERA, R. R  and  MENESES, V. M. C. CELLULOSE ACETATE MEMBRANES WITH ADJUSTABLE PORE SIZE. Rev. LatinAm. Met. Mat. [online]. 2002, vol.22, n.1, pp.38-41. ISSN 0255-6952.

In this work a description about the behavior of the porosity in membranes made from cellulose acetate and polyacrylic acid were carried out. In this description a mathematical model which describes the variation of the diameter of the pores was obtained. The results shows that the size of the pores vary as a function of the time employed during a thermal treatment. To obtain the mathematical model experimental data were analyzed by the use of the software Graphical Analysis.
