Abstract
The copolymers consisting of acrylic and methacrylic esters have achieved prime importance due to their versatile applications. Copolymerization of Methyl meth acrylate (MMA) with butyl acrylate has been carried out for modifying the properties of the polymer. Dynamic swelling kinetics were conducted at room temperatures to investigate the synthesized binder's swelling properties for paint industries. The experimental swelling curves were analyzed using three different models: Peleg's model, the first-order absorption kinetic model, and the exponential association equation model. All of these models demonstrated excellent agreement with the experimental data, as indicated by high R-Square values and low values for Chi Square, Sum of Squared Errors (SSE), and Root Mean Square Error (RMSE). Comparing the determination coefficients for these models, it was concluded that the Peleg model provides a better representation of the swelling characteristics across various concentrations of the crosslinker in the polymer. Specifically, the Peleg model exhibited high R-Square values of 0.98121, 0.9869, and 0.97605 for 0%, 5%, and 10% PPGDA concentrations, respectively. Furthermore, it yielded reduced chi-square values of 1.44546, 0.74895, and 0.86587 and root mean square error values of 1.202, 0.8654, and 0.9305 for the same respective concentrations. These results establish the Peleg model as the most favorable choice for characterizing the swelling behavior with different cross linker concentrations in the polymer. The prepared latexes are used as binder for environment friendly coatings.
