End functionalization of polyisoprene and polymyrcene obtained by anionic polymerization via one-pot ring-opening mono-addition of epoxides

Effect of tetrahydrofuran on the anionic copolymerization of 4‐trimethylsilylstyrene with isoprene

“…In addition, all samples were analyzed by thermogravimetric analysis under nitrogen to investigate their thermostability. All samples showed a similar degradation temperature (T 5% ) of 330-350 C, at which a loss of 5 wt% occurred (see Table 2 and Figure S19); this is in the range of the homopolymers P(TMSS): 320 C 47 and PI: 393 C. 3 All polymers showed a one-step degradation and a complete decomposition at about 500 C.…”

“…Since the discovery of living anionic polymerization in 1956, both industry and research have been using this technique to produce polymers with tailored properties, in particular block copolymers and other high-performance materials. [1][2][3][4][5][6][7][8][9] Most frequently, the products are based on styrene and diene monomers, which are polymerized under specific conditions to obtain nanophase-separated multiblock structures, which are used as thermoplastic elastomers.…”

Recent progress and applications enabled via electrochemically triggered and controlled chain-growth polymerizations

“…174 Under appropriate conditions, eAP shares the characteristics of conventional AP with chain termination or chain transfer reactions absent as the reactions demonstrate the characteristics of a living polymerization. At the end of the polymerization, adding quenching agents (water, 175 alcohol, 176 acid, 177 amine, 178 epoxides 179 ) can controllably quench the living anionic chain-end to introduce a range of functionalities at the polymer chain end. The generation of a carbanion is a reductive process and in eAP three possible modes of initiation have been described, namely:…”

Synthesis of phase-separated super-H-shaped triblock architectures: poly(l-lactide) grafted from telechelic polyisoprene

“…Tonhauser et al 16 demonstrated that glycidyl ethers are ideally suited to introduce multiple hydroxy groups at a living anionic chain end, leading to multifunctional macroinitiators. 17 This technique was recently used by Haddleton et al 18 to introduce a variety of different end groups at PI and polymyrcene, capitalizing on different substituted epoxides.…”
