“…It is well reported that the increase of the side-chain length leads to a decrease in T g values for both poly(methacrylate)s and poly(itaconate)s. − However, the values obtained in the present work are quite close to those observed for PMMA and poly(dimethyl itaconate) , polymers with considerable shorter side chains. Following this idea, poly( n -propyl methacrylate) ( T g ≈ 35 °C), poly( n -butyl methacrylate) ( T g ≈ 19 °C), poly( n -propyl methyl itaconate) ( T g ≈ 63 °C), and poly( n -butyl methyl itaconate) ( T g ≈ 42 °C) , can be considered as analogue polymers for PCNMA, PSO 2 MA, PCNMeiT, and PSO 2 MeiT, respectively, and present considerably lower transition temperatures. Higher T g values are observed for polymers containing functional groups with higher dipole moment, demonstrating that dipole interactions could play an important role.…”

This work presents the synthesis of new poly(itaconate)s containing sulfone or nitrile pendant groups through conventional radical polymerization together with their characterization and comparison with poly(methacrylate)s containing identical groups. Structural and thermal characterization has been carried out in terms of Fourier transform infrared spectroscopy, differential scanning calorimetry, nuclear magnetic resonance, and thermogravimetric analysis. Characterized by broad band dielectric spectroscopy (BDS), all polymers showed dielectric constant values between 7 and 10 (at 25 °C and 1 kHz) and relative low dielectric loss values (≈0.02). BDS measurements showed, for all the polymers analyzed, notorious subglass transitions even at temperatures below −100 °C, resulting in a broad temperature interval in which these polymers exhibit high dielectric constant and could work without high losses. Therefore, these materials seem to be good candidates for dielectric applications such as energy storage, among others.

“…20 Due to the structural similarity to acrylic acid (2) and methacrylic acid (3), itaconic acid and the corresponding esters, such as dimethylitaconate (4) and dibutylitaconate (5), have been intensively studied as an alternative monomer or comonomer to poly(meth)acrylates over the last few decades (Scheme 1a). 3,[21][22][23][24][25][26][27][28][29][30][31] Applications for this kind of polymer are widespread and range from corrosion inhibition 32 to dental materials, 33,34 elastomers, 35 and drug-delivery. [36][37][38][39][40][41] However, so far there have only been few studies in the field of polyesters based on itaconic acid (Scheme 1b).…”

“…The mono-esterification of the itaconic acid by using an alcohol such as methanol is a simple strategy for solving this issue because the effect of electron withdrawing from the vinyl group will be suppressed [7]. In spite of a number of monoesters, diesters and mixed-esters of itaconic acid have been synthesized and polymerized by radical polymerization [8]. The simplest and most inexpensive polymer based on itaconic acid derivative is poly(monomethyl itaconate).…”

Electrical Properties of Poly(Monomethyl Itaconate)/Few-Layer Functionalized Graphene Oxide/Lithium Ion Nanocomposites

Poly(monomethyl itaconate) is outstanding because it is a glassy and dielectric polymer obtained from sustainable feedstock. Consequently, the study of the properties of its nanocomposites has gained importance. Herein, the electrical properties of nanocomposites based on poly(monomethyl itaconate) and functionalized few-layer graphene oxide (FGO) in the presence and absence of lithium ions (Li+) are studied. Not only did the electrical conductivities of the nanocomposites present values as high as 10−5 Scm−1, but also the dielectric permittivity of nanocomposites with (FGO) content lower than the percolation threshold was twice that of the pristine polymer, without presenting a drastic increase of the loss tangent. By contrast, nanocomposites containing Li+ ions presented significant increases of the permittivity with concomitant increases of the loss tangent. Moreover, it was determined that the presence of Li+ ions influenced the charge transport in the composites because of its ionic nature.
