Those hydrogen bonds between itaconic acid
and chitosan act as additional physical crosslinking in the gel and hence, their breakage leads to lower degree of crosslinking and therefore larger alcogel volume.
In addition, the peak at 3.3-3.6 ppm is due to methylene proton of itaconic acid
7.4 ppm for CH of fumaric acid.

Factors affecting the growth form of Aspergillus terreus NRRL 1960 in relation to itaconic acid
In this study, we used polypropylene grafted with itaconic acid
(PP-g-IA) as a novel compatibilizer to improve the dispersion effects that occur upon blending PP and EVOH.
N-isopropyl acrylamide (NIPAAm) (Aldrich, Milwaukee, USA), methacrylamide (MAm) (Merck, Darmstadt, Germany), methacrylic acid (MA) (Merck, Darmstadt, Germany) and itaconic acid
(IA) (Sigma, St.
The functional acid monomer type (i.e., vinylphosphonic acid, acrylic acid, methacrylic acid, and itaconic acid
), the partitioning of acid monomer in the polymer or aqueous phase during the emulsion polymerization and the role of the latex polymer particle size were investigated.
The modified elastomer must have a functional group that can interact with a carbonyl group such as maleic anhydride, phthalic anhydride, acrylic acid, maleic acid, itaconic acid
, epoxy, or a glycidyl group.
In our previous work, we reported the synthesis, and the structural and thermal characterization of fully renewable BDIS [5, 6] copolyamides from itaconic acid
(IA), sebacic acid (SA), 1,10-decanediamine (DD), and 1,4-butanediamine (BD).
Plus, the itaconic acid
used to produce the copolymer is a renewable resource.
In this study, an attempt has been made to synthesis a pH responsive and temperature responsive (both characteristic being present in one) smart hydrogel by using copolymers made from acrylamide (AAm) as nonionic monomer; and an anionic monomer; itaconic acid
MSA was produced from catalytic hydrogenation of itaconic acid
which is renewable product.
