“…It is on this approach that the more interesting research on the preparation of biomass-based NIPU by biomass materials such as soybean oil and rapeseed oil have been already presented. Such a kind of biobased NIPU has been used for coating, plastics and rigid foams [12,13,14,15,16,17].…”

A partially biobased self-blowing and self-hardening polyurethane foam from glucose-based non-isocyanate polyurethanes (g-NIPU) was prepared by reaction of glucose with dimethyl carbonate and hexamethylene diamine. However, these foam types generally require a high foaming temperature. In this paper, a self-blowing foam based on g-NIPU was prepared at room temperature by using maleic acid as an initiator and glutaraldehyde as a crosslinker. Water absorption, compression resistance, and fire resistance were tested. Scanning electron microscopy (SEM) was used to observe the foam cells structure. Middle infrared (ATR FT-MIR) and Matrix Assisted Laser Desorption Ionization Time-of-Flight (MALDI-TOF) mass spectrometry were used to help to analyze the reactions during the foaming process. The results obtained showed that self- blowing rigid foams have good compression, this being directly proportional to the foam density. Increasing the amount of glutaraldehyde or reducing maleic acid thickens the cell walls and increases the density of the foams. MALDI-TOF analysis showed that g-NIPU reacts with both maleic acid and glutaraldehyde. The foams presented poor fire resistance indicating that, as for isocyanate based polyurethane foams, addition of a fire retardant would be necessary.

This study deals with the synthesis of vegetable oil (VO)-derived formulated resins with high bio-based content (30–77%) as potential renewable alternatives to conventional fossil-based vinyl ester (VE) and unsaturated polyester (UP) resins. First, epoxy acrylate was synthesized from a commercial epoxy resin via acrylation with acrylic acid. Then, acrylated epoxidized sesame oil (AESSO) and maleated castor oil (MCO) were synthesized and spectrally characterized. Afterward, networks of VE, AESSO, and MCO or their binary blends were prepared. The curing trend of the resins was investigated by differential scanning calorimetry. According to thermal and thermomechanical analysis, all of the VO-based networks possessed slightly inferior properties compared to those of VE. However, the adhesion strength of the VO-based alloying systems was higher than that of their petroleum-based counterpart based on T-peel and lap shear tests. Overall, it was concluded that the bio-resourced alloys could be considered as good alternatives to VE and UP resins, and the novel bio-resin formulations may be designed for adhesives, the polymer–matrix composites, and surface coating applications.

“…In recent years, the PU sectors have been promoting the use of green resources because of its long-term viability and suitability as a medium for polymer production. Green resources, such as lignin and its derivatives, [14] vegetable oils and their transesterification products, such as fatty acids and glycerol, [8,10,15] vanillin, [16] tannin, [17] terpenes, [18] limonene, [13a,18] D-mannitol and D-sorbitol, [19] and isosorbide, [8,20] have been used as starting raw materials for this purpose. Several studies have already reported the possible synthetic routes for efficient 5-membered CC preparations using these raw materials and their subsequent utilization in BPHU synthesis.…”

“…In general, TA can be carbonated either through preliminary carbonation via DMC or glycidylation by producing epoxidized TA and their subsequent CO 2 fixation through facile chemical methods. TA‐CC is then used as a starting monomer for TA‐based BPHU synthesis [17c] (Scheme 4).…”

New and emerging demand for polyurethane (PU) continues to rise over the years. The harmful isocyanate binding agents and their integrated PU products are at the height of environmental concerns, in particular PU (macro and micro) pollution and their degradation problems. Nonisocyanate poly(hydroxy urethane)s (NIPUs) are sustainable and green alternatives to conventional PUs. Since the introduction of NIPU in 1957, the market value of NIPU and its hybridized materials has increased exponentially in 2019 and is expected to continue to rise in the coming years. The secondary hydroxyl groups of these NIPU's urethane moiety have revolutionized them by allowing for adequate pre/post functionalization. This minireview highlights different strategies and advances in pre/post-functionalization used in biobased NIPU. We have performed a comprehensive evaluation of the development of new ideas in this field to achieve more efficient synthetic biobased hybridized NIPU processes through selective and kinetic understanding.
