Facile synthesis of environmental friendly halogen-free microporous terpolymer from renewable source with enhanced physical properties

Copolyethersulfones of 1,4:3,6-dianhydrohexitols and bisphenol A

“…[1][2][3] This is of increasing interest not only because it is associated with the abundance of these sustainable resources, but also because it gives the possibility to substitute petroleum-based products with environment-friendly chemicals. [4,5] In this respect, many studies in the last decade have been devoted to the development and synthesis of biosourced materials such as polymers and copolymers deriving from natural products. [6] The aim of this work was the elaboration of a novel copolyethersulfones starting from biosourced diols from corn starch in a simple and efficient step growth polymerization.…”

Spectral and thermal investigation of designed terpolymers bearing p-acetylpyridine oxime moieties having excellent antimicrobial properties

“…The Flynn-Wall-Ozawa method [23] has been used to determine the activation energy from dynamic tests by plotting the logarithm of heating rate as a function of the inverse of the temperature at different conversions. Being integrated with the initial condition of α = 0 at T = T o , Equation (4) can be arranging as follows:…”

Preparation and characterization of bio-based terpolymer derived from vanillin oxime, formaldehyde, and p-hydroxyacetophenone

“…[18] Figure 8 shows the Z(α) -α master and experimental curve of the terpolymer. The result indicates that terpolymer undergoes through D 2 (two dimensional diffusion) mechanism which means it releases monomer, dimmer, and trimer by chain scission and cationic biocides by side group elimination diffuses onto cell wall of microbes for the achievement of efficient biocidal material.…”

“…Moreover, Flynn-Wall-Ozawa method [18] has been used to determine the activation energy from dynamic tests by plotting the logarithm of heating rate as a function of the inverse of the temperature at different conversions. It can be given as…”

“…[16] Moreover, renewable resource-based furan resins were prepared with good thermal and biocidal properties for biomedical applications. [17][18][19] In this work, the synthesis and characterization of terpolymer derived from vanillin, p-hydroxyacetophenone (HA), and formaldehyde in the presence on an acid as catalyst is reported. The obtained terpolymer was fully characterized by Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance ( 1 H NMR) spectroscopy, and gel permeation chromatography (GPC).…”
