dc.description.abstractHigh amylose was cross-linked with sodium trimetaphosphate (STMP) using 2% and 4% solutions of NaOH at room temperature with reaction contact times of 0.5, 1, 2 and 4 h. The different polymers obtained were analyzed by FT IR, C-13 and P-31 solid state NMR, SEM and C, H and P elemental analysis. The results were used to propose a two-stage mechanism for phosphate incorporation, the first being kinetically controlled. (C) 2008 Elsevier Ltd. All rights reserved.en
