From glycidyl carbonate to hydroxyurethane side-groups in alternating fluorinated copolymers

Solubility-governed architectural design of polyhydroxyurethane-graft-poly(ε-caprolactone) copolymers

“…12,13 Carbonate, ester and ether, 14 thioether, 15 sulfone, 16 siloxane, 17 amide 18 and tertiary amine 19 groups or longer segments of oligo-esters, -ethers and -carbonates, 20,21 have for instance been reported along the backbone of linear PHUs, yielding diverse microstructures. Hydroxyurethane moieties have also been incorporated as side-groups in fluorinated, alternating copolymers 22 and polyester-graft-poly(ethylene glycol) brush copolymers, 23 and recently biobased ester-urethane star polymers based on glycerol and dimethyl-2,5furan dicarboxylate were reported. 24 Hence, PHUs with diverse microstructures can be achieved and hydroxyurethane functionalities can be used to decorate various polymer backbones, but copolymers with a PHU block or more complex architectures are lacking, especially when considering synthesis conditions devoid of solvents and hazardous reagents.…”

Synthesis and properties of POSS-containing gallic acid-based non-isocyanate polyurethanes coatings

“…Especially, NIPUs prepared from renewable natural resources have been described extensively for their low cost, biocompatibility and possible biodegradability [12][13][14][15][16][17][18]. Recently, for the purpose of improving the properties of NIPUs, several modifications have been exploited [19][20][21][22][23].…”

“…The chemical structures of the resulting products were characterized by FT-IR, 1 H NMR, and 13 C NMR. As well as, the properties of the NIPUs and POSS-containing NIPUs were determined.…”

Recent Advances on Quasianhydrous Fuel Cell Membranes

“…The chemical modification of GCVE units by isopropylamine as a model reaction [53] enabled one to find out the best conditions for further successful crosslinking of these terpolymers via the reaction of cyclocarbonate function with two telechelic aliphatic diamines: 1,3-propanediamine (DiA) regarded as a rigid diamine that bears a C3 chain length and tetraethylenepentamine (TEPA, Figure 13.9) as a more longer and softer diamine that contains four ethylene bridges separated by secondary amino functions (Figure 13.9). Actually, two amino end groups are primary and are more reactive than the three secondary ones (in TEPA) about cyclocarbonate groups.…”
