Poly(propylenefumarate phthalate)and acrylic acid radical copolymerization constants and parameters

Abstract

Poly(propylene fumarate phthalate) and acrylic acid radical copolymerization constants and parameters Poly(propylene fumarate phthalate) and acrylic acid radical copolymerization in dioxane solution at various molecular ratios of original monomeric mixture was studied in this work for the first time. An unsaturated polyester resin was obtained using the polycondensation reaction. The composition of the obtained poly(propylene fumarate phthalate) was determined according to elemental analysis. The studied copolymers are promising for further study due to their swelling ability, antioxidant activity, and biodegradable ability. Copolymerization reaction kinetics has been studied. The composition of the copolymers was determined using chromatemass spectrometry. Radical copolymerization constants and parameters have been calculated by Mayo-Lewis integral method. Based on the copolymerization constants the Q-e parameters was calculated according to the Alfrey-Price equation. It was proved that non-solvable polymers of a net-shaped structure are formed in the whole range of the researched comonomer ratios during the radical copolymerization of p-PFF with AА. Based on the results presented in the article, we can say that all copolymer compounds based on poly(propylene fumarate phthalate) and acrylic acid demonstrate the ability to control physical and chemical properties. This in turn will allow to create new materials with a pre-defined behavior program. It was found that the unsaturated polyester resin is characterized by a lower reactivity in case of acrylic acid and poly(propylene fumarate phthalate) copolymerization.

Research the Thermal Decomposition Processes of Copolymers Based on Polypropyleneglycolfumaratephthalate with Acrylic Acid

“…There is an apparent explanation for that, their factor contributes to a significant simplification and reduction in the cost of the work process, an increase in product quality, and production without harming the health of employees and the environment [ 7 , 8 ]. These properties are primarily expressed in polyester resins, thereby they appear in polycondensation polymers quite clearly [ 9 , 10 , 11 , 12 ]. All this has led to active growth in their use and to the emergence of a wide range of fundamentally new methods of production, processing, and use [ 13 ].…”
