Optimization of Epoxidation Palm-Based Oleic Acid to Produce Polyols

Optimization of epoxidation by using response surface methodology (RSM) based on three-level three-factorial central composite design (CCD) was used. Response percentage of relative oxirane content (%RCO) was studied to determine the optimum reaction condition for production of polyols. The predicted value of model (85 %) was excellent in accordance to experimental value (81 %).

THERMOMECHANICAL PROPERTIES OF COMPOSITIONS BASED ON POLYAMIDE 6, OBTAINED FROM THE SOLUTION

Thermomechanical studies of polamide 6 compositions, modified with (MPM) montmorillonite-polyvinylpyrrolidone mixture, were performed. Polyamide 6 nanocomposites were obtained by the solution deposition. The influence of nanocomposite production conditions on morphological features of polymer blends were researched. Determination of thermomechanical properties makes it possible to define the optimal content of MPM in polyamide 6 blends.
