Cross‐Linkable Liquid‐Crystalline Biopolyesteramide as a Multifunctional Polymeric Platform Designed from Corn Oil Side‐Stream Product of Bioethanol Industry

Abstract

A tunable biopolyesteramide platform is designed from the corn oil (CnO) side‐stream product of bioethanol industry. The (trans)amidation of CnO by diethanolamine (DEA) leads to the generation of a diol monomer (MCnO). The subsequent polymerization of MCnO with maleic anhydride (MA) generated a new kind of branched and brushed amphiphilic polymer (PCnO). This explorative investigation aims to understand the relationship between the reactivity, topology, self‐organization, and photoluminescence properties of PCnO and its cross‐linked homologous (CPCnO). This strategy offers an easy, inexpensive, and versatile way to design sustainable and soft smart materials.

Green Toughness Modifier from Downstream Corn Oil in Improving Poly(lactic acid) Performance

“…The chemical structure of received DCO from the bioethanol industry was evaluated by the 1 H NMR spectrum in Figure S1 of the Supporting Information. The presence of on average 1.53 carbon–carbon double bonds was found per fatty acid chain in DCO . This indicates that DCO is quite similar to regular corn oil. , The characteristic peaks of epoxy protons were found in the region of 2.9–3.2 ppm in the 1 H NMR spectrum of ECO (Figure a) .…”

Polyols from castor oil (Ricinus communis) and epoxidized soybean oil (Glycine max) for application as a lubricant base

“…In a round bottom flask with a capacity of 250 mL, 0.1 mol of castor oil and 0.35 mol of diethanolamine (DEA) were added. The reaction took place at a stirring speed of 300 rpm, at temperature of 130°C for 12 h, the reaction scheme is illustrated in Figure 2 (Pin et al, 2019). Further purification treatment was performed as described for transesterification of castor oil.…”

“…The reaction took place at a stirring speed of 300 rpm, at temperature of 150°C for 7 h, the reaction scheme is illustrated in Figure 2. After the end of the reaction the product submitted to reduced pressure for 3 h (Pin et al, 2019). The reaction of TACO with maleic anhydride formed an intermediate product, which after the 3 h in vacuum generated the polyol ETACO.…”
