摘要: Maleated natural rubber (MNR) was prepared and used as a blending composition compatibilizer for of (STR 5L) cassava starch. The melt rheological behavior in terms Mooney viscosity, apparent shear stress, viscosity at 100°C were quantified. We found that the pure MNR gave lower than did those blends with data increased increasing quantity highest value observed blend MNR. follows: > STR 5L (as compatibilizer) compounds. Furthermore, properties levels (MNR). results described intermolecular interaction between polar groups starch molecules. Each compounded, their curing characteristics studied. compounds exhibited long delayed onset vulcanization approximately 10 min. retardation found, because accelerator (MBT) reacted anhydrides compound instead acting an accelerator. not curves all MNRs equilibrium maximum torque, while curve torque slight reversion. combination 5L. That is, short action. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 81: 2803–2813,
