Post-polymerization modification of Poly(vinylcyclopropanes): A potential route to periodic copolymers

Recent Developments in Ring-Opening Copolymerization of Epoxides With CO2 and Cyclic Anhydrides for Biomedical Applications

“…Typical post-polymerization reactions are usually carried out by covalent modifications of the polymer end groups, main chain, and side groups (Gauthier et al, 2009). Among them, thiol-ene click chemistry is the most widely used method (Geschwind et al, 2013;Ntoukam et al, 2020). Besides, the formation of block copolymers or graft copolymers, bearing distinctive block properties (Ghosh et al, 2020;Gregory et al, 2020), could also be a facile approach toward functional materials, such as self-assembled nanomaterials.…”

“…Moreover, excessive protonic functional groups may cause catalyst deactivation (Yi et al, 2019). Therefore, post-polymerization modification is an important means to realize multi-functionalities on ROCOP polymers, and the desired functional groups can be accurately connected to the polymer chain by different modification methods (Ntoukam et al, 2020). In addition, the functionalization of the polymer can be achieved without protecting and deprotecting processes for functional monomers.…”

Chemiluminescent self-reporting supramolecular transformations on macromolecular scaffolds

“…In fact, PPMs have been proven to be a useful tool to synthesise highly functionalized polymers, especially since conventional polymerization processes do not allow the direct polymerization of monomers decorated with multiple functional groups. [39][40][41] In addition to synthetic polymers, commercially available polymers (e.g. polybutadiene 42 ) can be decorated with a broad variety of functionalities to obtain innovative macromolecules with tailor-made properties.…”

Radical ring-opening polymerization of novel azlactone-functionalized vinyl cyclopropanes

“…[7][8][9] The linear repeating units possess unsaturated bonds which have been successfully used for radical thiol-ene post-polymerization modifications. 10 Therefore, the synthesis of PVCP with a high linear unit content within the polymer backbone is a topic of high interest. However, there are only a few examples of successful PVCP syntheses with predomi-nantly linear repeating units, using Atom Transfer Radical Polymerization (ATRP).…”

“…11,12 Nevertheless, according to previous studies, the formation of linear units in PVCP is strongly dependent upon the polymerization conditions as well as the monomer structure. [9][10][11][12] Due to the uncertainty in the quantity of available unsaturated linear units within the polymer chains, the thiol-ene reaction cannot be considered an optimal choice for the post-polymerization modification of PVCP polymers. Fortunately, the PVCP chain can be modified not only using thiol-ene backbone modification, but also via the modification of the side-chains of PVCP.…”
