“…[18a] The epoxide functionalization of its respective vinylene and vinylidene double bonds present in the ring and side group are only employed as an intermediate for linear polycarbonates synthesis. In addition to its usage as a solvent for coatings and as a fragrance, [41] it has also used in BPHU synthesis. Limonene enables higher CO 2 fixation than plant-oil-based CC-precursors.…”

“…[15a,51] OFAM plays a double role during the transformation of inorganic NPs into their hybrid form, in which À SiÀ OÀ bonds based protective layer form around the inorganic NPs via hydrolysis or condensation of alkoxy groups, while their terminal functional groups take part in pre/postfunctionalization of BPHU. Due to the easy and rapid process, researchers are fascinated to hybrid the inorganic NPs with OFAM such as aminopropyltrimthoxysliane (APTMS), [41] aminopropyltriethoxysliane (APTES), [59] cholorosilanes, [60] trialkoxysilanes [61] and 3-glycidoxypropyltrimethoxysilane. [62] These coupling agents are chemical substances that create a chemical bridge between the polymer matrix and the reinforcement.…”

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.

Polyurethane (PU) adhesives and coatings are widely used to fabricate high-quality materials due to their excellent properties and their versatile nature, which stems from the wide range of commercially available polyisocyanate and polyol precursors. This polymer family has traditionally been used in a wide range of adhesive applications including the bonding of footwear soles, bonding of wood (flooring) to concrete (subflooring), in the automotive industry for adhering different car parts, and in rotor blades, in which large surfaces are required to be adhered. Moreover, PUs are also frequently applied as coatings/paints for automotive finishes and can be applied over a wide range of substrates such as wood, metal, plastic, and textiles. One of the major drawbacks of this polymer family lies in the use of toxic isocyanate-based starting materials. In the context of the REACH regulation, which places restrictions on the use of substances containing free isocyanates, it is now urgent to find greener routes to PUs. While non-isocyanate polyurethanes (NIPUs) based on the polyaddition of poly(cyclic carbonate)s to polyamines have emerged in the past decade as greener alternatives to conventional PUs, their industrial implementation is at an early stage of development. In this review article, recent advances in the application of NIPUs in the field of adhesives and coatings are summarized. The article also draws attention to the opportunities and challenges of implementing NIPUs at the industrial scale.
