“…The material also offered good mechanical properties: ultimate elongation ε B = 420%, and true tensile stress δ B = 10 MPa. The grafting degree was determined on the basis of the water extraction results for free IA (IA is well‐soluble in water) that were presented in Ref 17…”

Polyethylene grafted with itaconic acid was subjected to weathering under laboratory accelerated conditions. The course of the photo-oxidative degradation process of that material was studied by FTIR spectroscopy both through quantitative measurements of changes in absorbance values at selected wave numbers and through measurements of surface area values for absorption bands which were separated by means of deconvolution. The use of both those procedures of quantitative determinations resulted in a general conclusion that the oxidation process was initiated from the very first moment of irradiation, and it produced ketones, acids, esters (intramolecular and of acetate type), peracids, peresters, hydroperoxides, and alcohols. The molecular weight values and gel number values, which were established as well, pointed out that oxidation was accompanied by cracking of polymer macromolecules, and also by polymer crosslinking to a limited degree.

“…Itaconic acid has a double bond in its molecular structure. − The chemical structure of itaconic acid gives it special chemical properties. It can be copolymerized with other monomers such as acrylonitrile, and can also undergo addition, esterification, condensation polymerization, and metathesis polymerization. − Because of the presence of carboxyl groups, itaconic acid can be used as a substitute for acrylic acid or methacrylic acid to polymerize with vinyl acetate, dimethyl maleate, etc., and the resultant resin has good water absorption properties . Itaconic acid can be used for adhesion with acrylic latex, and it is also added to paint to improve the quality.…”

Poly(ethyl acrylate-co-methoxyethyl acrylate-co-dialkyl itaconate-co-vinyl chloroacetate)s (PEMDAVs) were synthesized by redox initiated emulsion polymerization of ethyl acrylate, methoxyethyl acrylate, vinyl chloroacetate, and biobased dialkyl itaconate as a modified monomer. The molecular weight of the synthesized PEMDAVs was in the range of 337 000 and 346 000 g/mol, which was higher than that of the unmodified polymer PEMV. The structure and thermal performance of PEMV and PEMDAVs was determined by 1H nuclear magnetic resonance, differential scanning calorimetry, and thermogravimetric analysis. Carbon black (CB) was used as a filler to enhance the PEMV and PEMDAVs. Mechanical properties of PEMDAVs/CB nanocomposites got improved compared with PEMV/CB nanocomposite. In addition, we analyzed the effect of biobased monomer itaconate with different side chain length on the mechanical properties and oil resistance. It is worth noting that PEMDMV/CB with dimethyl itaconate content exhibited great heat oil resistance in ASTM #3 oil at 150 °C or even 175 °C. This work is expected to not only prepare excellent mechanical properties and oil-resistance elastomers but also provide some guidelines for the modified traditional rubber with biobased monomers.
