Investigation of Drying and Chemical Properties of Unstyrenated and Styrenated Palm Kernel Oil Modified Alkyl Resins Using Some Empirical Models

Abstract: The investigation of drying properties of unstyrenated and styrenated palm kernel oil modified alkyd resins using some empirical equations was studied. Three different alkyd resins A, B and C were prepared with dehydrated palm kernel oil, phthalic anhydride, maleic anhydride and glycerol using lithium hydroxide as catalyst at stipulated ratios. The prepared alkyd resins were post- polymerized with styrene using benzoyl peroxide as an initiator under reflux at 120°C for 3 hours. The drying and chemical behaviour of the alkyd resins and styrenated alkyd resins were investigated using standard methods. Some empirical model equations (linear, exponential, logarithmic and quadratic) were tested for the dynamics of the physical drying and chemical resistance of both styrenated and unstyrenated alkyds in terms of viscosity and conversion. All the resins showed good properties. The styrenated alkyd resins gave a faster drying time and displayed better chemical resistance. Unlike the unstyrenated alkyd which is only resistant to water, brine, and acidic media, the styrenated alkyds were also resistant to alkalis. It was found that quadratic model equation best describes the dynamics of the physical drying and chemical resistance of both the styrenated and unstyrenated alkyds resins. Therefore, it can be concluded that styrenated alkyd resins offer an improved applications in terms of drying and chemical resistance in surface coating purposes.
