Recent Advances in Vegetable Oil‐Based Polyurethanes

Abstract

Polyurethanes are among the most versatile polymers because of the wide range of monomers, particularly diols or polyols, that can be utilized in their synthesis. This Review focuses on the most recent advances made in the production of polyurethane materials from vegetable oils. Over the past several years, increasing attention has been given to the use of vegetable oils as feedstocks for polymeric materials, because they tend to be very inexpensive and available in large quantities. Using various procedures, a very broad range of polyols or diols and in some cases, poly- or diisocyanates, can be obtained from vegetable oils. The wide range of vegetable oil-based monomers leads to a wide variety of polyurethane materials, from flexible foams to ductile and rigid plastics. The thermal and mechanical properties of these vegetable oil-based polyurethanes are often comparable to or even better than those prepared from petroleum and are suitable for applications in various industries.

Vegetable oil-derived epoxy monomers and polymer blends: A comparative study with review

“…Vegetable oils such as linseed and tung oil are drying oils, which can self-crosslink under atmospheric oxygen, have long been used in the coating industry [3]. Semi-drying oils like soybean oil are of plentiful supply and therefore of relatively low cost, have also attracted great interest for the preparation of polymers or resins [4]. In recent years, with the rising cost of fossil raw materials and environmental issues, polymers derived from soybean oil have demonstrated strong cost/performance competitiveness in many market applications [5].…”

Vegetable oils: a source of polyols for polyurethane materials

“…4. Commonly used strategies to introduce OH groups into triglycerides and thus prepare polyols (Pfister et al, 2011;Nohra et al, 2013). petrochemical resources. This wide range of polyols brings PUs a plethora of different properties, making them suitable in many fields of applications (Engels et al, 2013).…”

“…A lot of efforts have been done to develop alternatives from vegetable oils. The synthesis of polyols and corresponding PU networks from vegetable oils has been already well reviewed in the literature (De Espinosa and Meier, 2011;Desroches et al, 2012a;Maisonneuve et al, 2013a;Pfister et al, 2011). Castor oil is an exception in vegetable oils with its naturally occurring hydroxyl groups and thus was studied in priority in PU synthesis (Mutlu and Meier, 2010;Ogunniyi, 2006).…”

Surface Film Adsorption and Lubricity of Soybean Oil In-Water Emulsion and Triblock Copolymer Aqueous Solution: A Comparative Study

“…Biodegradable, non-toxic, and environmentally friendly vegetable oil [11] with superior tribological properties than conventional mineral oil [12][13][14] is a potential mineral oil substitute. When used as vegetable oil in water emulsion (referred to as VO/W emulsion in this work), the heat convection property of the aqueous phase complements the friction reducing property of the oil phase [2].…”
