Sustainable thermoplastic elastomers derived from plant oil and their “click-coupling” via TAD chemistry

Abstract

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

Fabrication of well‐defined shape memory graft polymers derived from biomass: An insight into the effect of side chain architecture on shape memory properties

“…Elastic behavior of these SMPs was evaluated by step cyclic tensile tests that were performed at cyclic stretching deformation with a maximum strain of 50, 100, 150, 200, 250, 300, 350, and 400%. Similar to early reports on the cellulose graft copolymers, all these SMPs exhibited elastomeric behavior. As shown in Figure (a,b), it can be clearly seen that the elastic recovery values of EC‐ g ‐(PLMA‐ b ‐P(LMA‐ co ‐THFMA700)) and EC‐ g ‐P(LMA‐ co ‐THFMA700) increased with the increasing of the maximum strain in each step.…”

Preparation of Janus nanoparticles from block copolymer thin films using triazolinedione chemistry

“…In recent years TAD-(di)ene click reactions were found very useful in the preparation of nanoparticles, 25 polymer bioconjugates synthesis of block co-polymers, 26 functionalization of polymers and materials etc. [27][28][29][30][31][32] In an earlier report, while demonstrating the rst example for the application of 'triazolinedione-ene' reactions to prepare nanoparticles, we have shown that this chemistry can be a useful platform to prepare spherical nanoparticles from multi-ene systems, such as plant oils, via a nanoprecipitation technique. 25 However, such methods cannot be applied for the preparation of asymmetric structures such as Janus particles.…”

Sustainable rubbers and rubber additives

“…Ganewatta et al . prepared thermoplastic elastomers from natural rosin and modified vegetable oil, and discussed other sustainable elastomers from renewable biomass . Plant based phenolic acids with varying functionalities were utilized to prepare thiol‐ene elastomers using a photoinitiator …”
