We report the preparation of plant oil based triblock copolymers as thermoplastic elastomers with the aid of TAD chemistry.

Sustainable fuels, chemicals, and materials from renewable resources have recently gained tremendous momentum in a global scale, although there are numerous nontrivial hurdles for making them more competitive with petroleum counterparts. We demonstrate a robust strategy for the transformation of plant oils into polymerizable monomers and thermoplastic polymer materials. Specifically, triglycerides were converted into N-hydroxyalkyl fatty amides with the aid of amino alcohols via a mild base-catalyzed amidation process with nearly quantitative yields without the use of column chromatography and organic solvents. These fatty amides were further converted into a variety of methacrylate monomers, cyclic norbornene monomers and imino ether monomers. Representative polymers from selected monomers exhibit drastic different physical properties with subtle structural variations, highlighting the potential of this particular amidation reaction in the field of biomass transformation.

We report biomass-derived, shape-memory materials prepared via simple reactions, including "grafting from" ATRP and TAD click chemistry. Although the biomass, including plant oils and cellulose nanocrystals, has heterogeneous chemical structures in nature, these materials exhibit excellent multiple shape-memory properties toward temperature, water, and organic solvents, which are comparable to petroleum counterparts. The work presented herein provides burgeoning opportunities to design the next-generation, lowcost, biomass-prevalent, green materials for niche applications.

Amidation of plant oils with amino alcohols was methodologically examined.

Single crystals of Na 5 RE 4 IJOH)ijSiO 4 ] 4 (RE = Pr, Nd, Sm, Eu, Tb-Yb, Y) were grown using the hydroflux synthetic method. All compositions adopt the tetragonal I4 space group with lattice parameter ranges of a = 11.5275IJ4)-12.0588IJ3) Å and c = 5.3951IJ4)-5.4846IJ13) Å. Intense photoluminescent properties were observed for Na 5 Eu 4 IJOH)ijSiO 4 ] 4 , Na 5 Gd 4 IJOH)ijSiO 4 ] 4 , and Na 5 Tb 4 IJOH)ijSiO 4 ] 4 . The magnetic susceptibility was measured for the magnetic rare earth containing compositions, where the terbium analogue displayed antiferromagnetic order at T = 2.8 K. Among the many different classes of structures explored for use in solid state lighting, alkali metal containing silicate and germanate structures such as Na 3 have been studied extensively. A similar structural family, A 5 RE 4 XijTO 4 ] 4 , [A = alkali metal, RE = rare earth, T = tetragen] contains several known compounds in closely related structure types, and includes Na 5 Nd 4 IJOH)ijSiO 4 ] 4 , 24 Na 5 Y 4 FijSiO 4 ] 4 , 25 K 5 La 4 FijSiO 4 ] 4 , 26 Na 5 Nd 4 Ge 4 O 16 IJOH), 27 and IJNa 0.63IJ2) Nd 0.37IJ2) )IJNaSiO 4 ) 4 IJO 0.52 F 0.48 ). 28 As most rare earths can be accommodated in this tetragen based structure type, it represents an attractive host material for new, rare earth based, luminescent materials.Herein, we report the synthesis of alkali metal containing silicates Na 5 RE 4 IJOH)IJSiO 4 ) 4 (RE = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Y) using the hydroflux technique.
