Preparation of multi-allylic dendronized polymers via atom-transfer radical polymerization

Abstract: Atom-transfer radical polymerization (ATRP) was investigated to polymerize a styrene monomer carrying carbosilane dendrons with 6 terminal allyl branches. Polymers with a monomodal molar mass distribution and low polydispersity have been produced, while by comparison the free-radical polymerization technique led to chain transfer early in the polymerization. Steric effect brought by the dendrons result in a slow polymerization rate, leading to an apparent saturation of the degree of polymerization. By pushing … Show more

“…However, NIPAAm could change the surface structure when the reaction temperature closed to the LCST as a temperature-responsive monomer. 42 Based on steric effect theory, 43,44 the reaction rate at 33 C decreased due to the increase of steric effect by the shrink structure of pNIPAAm polymer brushes (Figure 1(e)). In conclusion, the optimal reaction conditions for industrial application were as follows: FL 0.13 mmol/L, CPADB 1.33 mmol/L, NIPAAm 1.47 mol/L, 20% DMF aqueous solution in the presence of oxygen at 23 C.…”

“…To date, several synthesis processes have successfully been applied for the preparations of allyl-terminated polymers, and several post-modification strategies have been effectively utilized. The most common synthesis methods of allyl-terminated polymers are ring-opening polymerization (ROP) [36][37][38][39][40][41][42], anionic ring-opening polymerization [43], reversible addition-fragmentation chain transfer (RAFT) polymerization [44], atom transfer radical polymerization (ATRP) [45][46][47], and condensation reactions [48][49][50]. The thiol-ene photoinitiated, or thermal polymerization, method is the method most vastly applied for the post-functionalization of allyl (ene) polymers.…”
