“…277,278 Recently, Chikkali et al introduced challenging sugar-derived hydrophilic monomers into polyethylene chains through coordination insertion polymerization. 279 They copolymerized sugar-derived isohexide monoenes, including isomannide and isosorbide monoenes or methacryl-2,3,4,6-tetra-Oacetyl-D glucopyranoside with ethylene using Pd-phosphine sulfonate acetonitrile catalyst (catalyst activity = 0.1−1 kg mol −1 h −1 , M w = 13−28 kg mol −1 ). High-temperature 1 HNMR results revealed 1.45% of the biobased monomer enchainment where the comonomer incorporation slightly affected the crystalline structure of polyethylene and endowed copolymers with melting temperatures in the range of 117−126 °C.…”

Polyolefins play a crucial role in the polymer industry because of their low-cost monomers and well-established production processes. Recent years have witnessed tremendous progress in direct and tandem copolymerization strategies that provide an opportunity of developing polyolefins bearing polar groups with distinctive architectures and properties. In this perspective, we first highlight new routes for the proficient synthesis of tailor-made functional polyolefins and briefly discuss their designing tactics. Then, we attempt to categorize these, recently appeared in the literature, innovative functional polyolefins on the basis of their applications. The prospected future applications of polar olefin copolymers include biomedical materials, catalysts, energy storage devices, and conductive polymers, which open up new arenas and paradigms for academic research and industrial products development. Critical issues concerning intelligent functional polyolefins and green chemistry are discussed, too.

“…30 Chikkali and co-workers reported copolymerization of ethylene and sugar derived isohexide monoenes (M4 and M5, Scheme 1b) catalyzed by a phosphine-sulfonate palladium catalyst with low comonomer incorporation (1.45%). 31 The above examples prove that it is not facile to obtain satisfactory polymerization results. To solve this, the norbornene-based comonomers were taken into consideration due to their unique copolymerization properties: (i) the long spacer between the polar functional group and the double bond makes them only mildly poisoning toward the metal center; (ii) the cyclic structure makes them less prone to βhydride elimination and the corresponding chain transfer reaction; (iii) the strong π-donating ability enables strong binding affinity to the metal center.…”

Introducing polar biomass groups into polyolefins can not only improve their nonpolar nature but also conform to the concept of sustainable development. Now, an efficient route to generate polar functionalized polyolefins with high biomass content is reported. Two kinds of bioresourced comonomers are designed by assembling biomass groups (oleyl and cinnamyl groups) with the norbornene structure and inserted into the polyolefins by phosphine-sulfonate palladium-catalyzed copolymerization reactions. The norbornene spacer in the comonomers leads to great ethylene copolymerization results of catalytic activities (3.3 × 10 5 to 2.04 × 10 6 g mol −1 h −1 ), polymer molecular weights (68,000−188,000 g mol −1 ), and comonomer incorporations (1.9−22.4 mol %). Meanwhile, the insertions of these comonomers can easily tune the various properties of polyolefin materials, such as thermal, mechanic, surface, and optical properties. Furthermore, the deliberately introduced internal carbon−carbon double bonds in the biomass groups provide further reactive sites for sulfur vulcanization to enhance the tensile strength of copolymers. Two kinds of reversible dynamic cross-linked networks can also be built based on these carbon−carbon double bonds and endow the obtained polymers with good remodeling performances.

Due to the depletion of fossil fuels, higher oil prices, and greenhouse gas emissions, the scientific community has been conducting an ongoing search for viable renewable alternatives to petroleum-based products, with the anticipation of increased adaptation in the coming years. New academic and industrial developments have encouraged the utilization of renewable resources for the development of ecofriendly and sustainable materials, and here, we focus on those advances that impact polyurethane (PU) materials. Vegetable oils, algae oils, and polysaccharides are included among the major renewable resources that have supported the development of sustainable PU precursors to date. Renewable feedstocks such as algae have the benefit of requiring only sunshine, carbon dioxide, and trace minerals to generate a sustainable biomass source, offering an improved carbon footprint to lessen environmental impacts. Incorporation of renewable content into commercially viable polymer materials, particularly PUs, has increasing and realistic potential. Biobased polyols can currently be purchased, and the potential to expand into new monomers offers exciting possibilities for new product development. This Review highlights the latest developments in PU chemistry from renewable raw materials, as well as the various biological precursors being employed in the synthesis of thermoset and thermoplastic PUs. We also provide an overview of literature reports that focus on biobased polyols and isocyanates, the two major precursors to PUs.
