Polymerization of itaconic acid initiated by a potassium persulfate/N,N‐dimethylethanolamine system

Abstract

ABSTRACT:The synthesis and characterization of poly (itaconic acid) (PIA) with a novel initiator/activator system is presented. The initiator in this system was potassium persulfate, whereas the activator was N,Ndimethylethanolamine (DMEA). PIA was synthesized in distilled water and in 0.1M HCl at 40 C with reaction times of 72 and 96 h. PIA was investigated with differential scanning calorimetry, gel permeation chromatography, and pulse gradient spin echo-NMR and compared to the same polymer synthesized in dioxane with 2,2 0 -azobisisobutyronitrile as the initiator. It was shown that, despite the fact that some residual DMEA remained in the system, the properties of the PIA polymerized in the aqueous phase were very similar to the dioxane-synthesized polymer, which will enable a faster, cheaper, and environmentally more acceptable polymerization of itaconic acid.

Synthesis and characterization of waterborne polyurethane emulsions based on poly(butylene itaconate) ester

“…[10][11][12] IA is a dicarboxylic acid produced by fermentation as one of the key platform chemicals derived from biomass. The IA-based polyester has been synthesized through condensation polymerization of the carboxyl groups of IA and the hydroxyl groups of butanediol.…”

Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater

“…According to the producer data, its molecular weight is 100 000-300 000 g/mol, degree of deacetylation 80 %. Poly(itaconic acid) (PIA) was prepared in our laboratory by polymerization of aqueous solution of itaconic acid in 0.1 M HCl (Molar mass of the obtained PIA, measured by limiting viscosity number was M v ¼ 48 kDa) by our previously reported procedure (Velickovic et al 2008). Reactive Orange 16 (also known as Remazol Brilliant Orange 3R, or Bezactiv Orange V-3R) was a gift from Bezema AG and was used as received.…”

Novel biosensor films based on chitosan

“…The degree of deacetylation, determined by potentiometric titration is 80% [14]. Poly (itaconic acid) (PIA) was prepared in our laboratory by our previously reported procedure [15].…”

“…In temperature range from 155-228°C two closed peak on PIA thermogram can be observed. The first one is assigned to the formation of poly(anhydride) with evaporation of water and reaches maximum at 183°C, while the second one is assigned to the decarboxylation and reaches maximum at 208°C [15].…”
