Efficient room-temperature synthesis of crosslinked polyhydroxyurethanes from 5-membered cyclic carbonates without solvent or catalyst
Efficient room-temperature synthesis of crosslinked polyhydroxyurethanes from 5-membered cyclic carbonates without solvent or catalyst We report the first solvent- and catalyst-free synthesis of crosslinked polyhydroxyurethanes (PHUs) at room temperature from five-membered cyclic carbonates (5CC). A trifunctional carbonate (tri-5CC) combined with tetraethyleneglycol diamine (tDA) formed homogeneous, gelled networks within 24 h (carbonate conversion = 90%, gel time = 6 h).
Optimized synthesis of a High Oleic Sunflower Oil derived Polyamine and its Lignin-based NIPUs
Optimized synthesis of a High Oleic Sunflower Oil derived Polyamine and its Lignin-based NIPUs In the continuing effort towards reducing reliance on fossil resources, the transition to biobased materials is of utmost importance together with the adoption of more sustainable and safe production processes.

Sequential acid-catalyzed alkyl glycosylation and oligomerization of unprotected carbohydrates
Sequential acid-catalyzed alkyl glycosylation and oligomerization of unprotected carbohydrates An efficient method has been developed to synthesize end-functionalized oligosaccharides from unprotected monosaccharides in a one-pot/two-step approach. In the first step, mannose (and glucose) were functionalized with an alkyne group at the anomeric position through Fisher-glycosylation reaction with propargyl alcohol as glycosyl acceptor.
Hyperbranched Polyesters by Polycondensation of Fatty Acid-based ABn-type Monomers
Widely available vegetable oils were readily derivatized into chemically pure ABn-type monomers (n = 2 or 3). Their polymerization led to unprecedented hyperbranched polyesters. Four different AB2/AB3-type monomers bearing one A-type methyl ester and two or three B-type alcohol functions were purposely synthesized via two elementary steps, i.e. epoxidation of the internal double bond of the vegetable oil precursors followed by ring-opening of the epoxy groups in acidic conditions.
