Synthesis and characterization of ring-type and branched polymers including polyethylene glycols by “click” chemistry [PDF]

SN Applied Sciences, 2019
Synthesis of ring-type (or branched) polymers including polyethylene glycols was archived via “click” chemistry of 5,6-diazido-2-benzyl-1H-benzimidazole (Di-N3) [or triazidoacetohydrazide derivative (Tri-N3)] and terminally dipropargyl polyethylene glycols (PEG-dipropargyl) with different molecular weights.

Hyperbranched Polymers with High Degrees of Branching and Low Dispersity Values: Pushing the Limits of Thiol–Yne Chemistry [PDF]

Macromolecules, 2016
We propose a versatile approach to the production of hyperbranched polymers with high degrees of branching and low dispersity values (Đ), involving slow monomer addition of a thiol/yne monomer to multifunctional core molecules in the presence of photoinitiator and under UV irradiation.

Hyperbranched polymers with step-growth chemistries from transfer-dominated branching radical telomerisation (TBRT) of divinyl monomers

Polymer Chemistry, 2020
The commercially relevant synthesis of novel materials with step-growth backbones has been achieved by applying conventional chemistries to the radical telomerisation of divinyl monomers leading to high molecular weight branched polymers.
