“…Furthermore, Kong et al [76] proposed an inexpensive combination of hydroxylation and transesterification with 1,2-and 1,3-propanediol in order to increase the polyol functionality and to reduce the molecular weight and viscosity of the resulting polyurethanes, increasing their resistance to hydrolysis and alkali attack. The polyol obtained from the combination of those modifications succeeded in such a way that it was quickly marketed by the name of Liprol™ (Meadow Polymers, Consolidated Biofuels Ltd., Canada), which would be further used in conjunction with cellulose nanocrystals to prepare polyurethane nanocomposites [77]. Another pioneering study is that conducted by Norhisham et al [78], which addresses the production of biodiesel fuelbased polyols (fatty acid methyl ester) combined with palm olein polyol to synthesize elastomeric polyurethanes with greater natural content and an appropriate pressure-sensitive adhesive response, using boron trifluoride diethyl ether complex (BF 3 ) as the alcoholysis catalyst.…”

On account of the irreversible environmental damage caused by the utilization of non-renewable raw materials in industrial production, since the end of the twentieth century, the interest in replacing the traditionally applied petroleum-based starting compounds in the polyurethane production by more sustainable feedstocks has grown enormously. Such pursuit of Green Chemistry has been fostered by the implementation of a set of national and international initiatives and stricter regulations, especially in the field of adhesives. In this respect, the latest advances in the production of bio-based polyurethanes are collected in this review. Thus, after a brief introduction to this subject and main tendencies towards the production of more sustainable polyurethanes, the first section reviews the feasibility of manufacturing polyurethanes from a range of natural platforms, including lignocellulosic biomass and vegetable oils, whether modified or in their original form, along with some industrial wastes. Afterwards, the hitherto considered synthetic routes for the preparation of greener polyurethanes are assessed, encompassing waterborne, radiation-curable and non-isocyanate polyurethane techniques. Finally, the last section focuses on the research advancement on the synthesis, properties and different uses of bio-based polyurethanes specifically implemented in the field of adhesives.

“…[15][16][17][18][19][20][21][22] Moreover, partial replacement of petroleum-based polyols with biobased polyols is an alternative approach for the preparation of polyurethane for applications such as coatings, adhesives, sealant, elastomer, as well as flexible and rigid foams. [23][24][25][26][27][28][29][30][31][32][33][34][35] The possibility of utilising castor oil and crude glycerol to produce bio-based polyols and subsequently RPUFs was explored by Carrico et al 5 Different amounts and types of blowing agent (water, pentane and cyclo-pentane) and catalyst (DBTDL) were examined in the study. Increase amount of water content resulted in a decrease in density, thermal conductivity, compressive strength and Young's modulus.…”

Palm olein-based polyol (PP) was used as a partial replacement for commercial sucrose/glycerine initiated polyether polyol (GP) for the production of low density rigid polyurethane foams (RPUFs). The hydroxyl value (OHV) of the GP was 380 mg KOH/g, whereas the OHV for PP was 360 mg KOH/g. The RPUFs were prepared by replacing the GP with PP up to 50 parts per hundred parts of polyols (pph). Characterisation of the RPUFs, including density, compressive strength and strain, cell morphology and thermal conductivity ( k-value), were conducted. The dimensional stability of the foams was also evaluated. The study showed improvement in the compressive strength and strain for palm-based RPUFs with the incorporation of up to 30 pph PP as compared to GP foams. The lowest k-value (0.0232 W/m.K) of RPUF with density below 30 kg/m3 was obtained with the incorporation of 10 pph PP. This was due to the smallest and uniform pore size distribution observed using SEM images. The dimensional stability of the RPUF prepared from PP was within the acceptable range. Thus, the RPUFs made from PP are potential candidates to be used as insulation for refrigerators, freezers and piping.

“…Owing to an increase awareness on sustainable development to reduce environmental impact, carbon footprint and dependence on petrochemical-based resources, the usage of renewable resources as raw materials in polyurethane production is in increasing trends. [11][12][13][14][15][16][17][18] Polyester polyols, which are the second most important polyols in polyurethane production after polyether polyols, can be of 100% bio-based. Bio-based building blocks could be produced from renewable resources either through biotechnological process or chemical pathways.…”

Research and developmental work of bio-based materials from both renewable resources and biotechnological processes have gained significant interest recently. In this study, bio-based azelaic acid has been used in combination with succinic and adipic acids to synthesize co-monomeric polyester polyol soft segments for thermoplastic polyurethanes (TPUs). Hysteresis of TPUs made from co-monomeric polyester polyols were significantly lower in comparison to the reference TPUs made from monomeric polyester polyols, indicating significant improvement in dynamic properties. In addition, tensile sets of TPUs prepared with co-monomeric polyester polyols were lower compared to TPUs prepared from monomeric polyester polyols, confirming excellent dynamic properties. Improved dynamic properties of TPUs based on co-monomeric polyester polyols can be ascribed to a phase-separated morphology which was quantified as the lowest fraction of bonded urethane from FTIR spectra, reduced crystallinity in differential scanning calorimetry thermograms, narrow tan δ peaks measured using dynamic mechanical analyses, and images from atomic force microscopy.
