Preparation And Characterization of Alkyd Resin Polymer of Vegetable Oil Under the Influence of a Catalyst and A Kinetic Study of Its Polymerization
Keywords:
Alkyd Resins, Polymerization of Castor Oil, Effect of The Catalyst on The Polymerization Reaction, FTIR, 1HNMR, Activation Energy Ea.Abstract
The study included the preparation of a polymer (alkyd resin) in two steps: the first is the preparation of monochlorides from the reaction of glycerine with castor oil in the presence of catalysts (Pb2O3, LiOH) and at a temperature (150 ˚C). A catalyst (CaCO3) and a range of temperatures (210, 200, 190, 180, 170) ˚C. The polymer was studied and identified by: infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1HNMR), and adhesiveness test. The molecular weight of the polymer was calculated by means of gel permeation chromatography (GPC) and calculated by means of viscometric viscosity through the graph of the polymer .The kinetics of the polymerization reactions was studied by tracking the decrease in the acid value and the amount of water removed from the reaction medium of the polymer prepared using the catalyst (CaCO3). ). The activation energy (Ea) and frequency coefficient (A) were calculated from the Erinus equation. And calculating thermodynamic functions (ΔH˚, ΔS˚, ΔG˚).
