Polypropylene Glycol Maleate Phthalate Terpolymerization with Acrylamide and Acrylic Acid

Popis výsledku v původním jazyce

The possibility of synthesizing new multifunctional terpolymers based on polypropylene glycol maleate phthalate with acrylamide and acrylic acid was shown. The basic laws of the process of radical terpolymerization in a dioxane medium were studied at various molar ratios of the reactants. The block length, transition probabilities, and Harwood block parameter of the terpolymers synthesized, which reflect information on the location of macroradicals in the chain, were calculated. The radical terpolymerization constants, indicating the possibility of copolymers to form structures with a free distribution of units, were calculated with the help of the Mayo-Lewis equation. The method of scanning electron microscopy was used to study the surface morphology of polymers and to evaluate the surface pore sizes. There were carried out investigations on the effect of pH of the medium and organic solvents on the degree of swelling of the samples studied. Using thermogravimetric analysis, the thermal decomposition of the synthesized terpolymer based on polypropylene glycol maleate phthalate with acrylamide and acrylic acid was studied. The features of mass loss and thermal transformations upon heating were revealed. It was found that the process of thermal degradation intensified in the range of 339-428 degrees C with the maximum weight loss of the sample similar to 78.64%.
