“…Thus, they introduce more free volume to the cluster regions without affecting the amount of the cluster regions. [36][37][38][39] In this study, the calcium carbonate is used both for a nanofilling effect and the ionic sites formation by its partial reaction with the acid pendant functions in the main polymer chain, leading to important changes in the physical properties of the material. When the length of the organic chain attached to the salt is high enough, the free volume introduced in cluster regions is so big that no filling effect is observed.…”

To create reversible supramolecular ionic networks, ionic cross-links were formed from acid pendant functions in poly(styrene-co-methacrylic acid) copolymers by the addition of calcium carbonate. The random dispersion of acid functions in the polystyrene chain is ensured by NMR analysis. The partial reaction of the calcium carbonate with the carboxylic acids is highlighted by a limewater test. The influence of methacrylic acid and calcium-carbonate contents on the formation of an ionic network has been studied through solubility tests. Two main effects were obtained: the exfoliation of the unreacted calcium carbonate characterized by TEM is due to ionic interactions at the surface of nanometric particles that form the first level of organization of the calcium carbonate. Another part of the calcium carbonate reacts with carboxylic acid and is detached from particles to form clusters as shown by x-ray analysis. Finally, by analyzing the dynamic rheological spectrum, the conclusion that the strength of the ionic bonds arises with the calcium content is made. The interest of such an approach with a wide range of observed phenomena in the material is a one-batch process to make thermoreversible nanocomposite networks.

“…These HEMA‐terminated‐polyester macromonomers have been used in copolymerization with other (metha)acrylic monomers, to produce graft‐copolymers via controlled radical polymerization techniques such as ATRP and RAFT . However, the majority of the HEMA‐based polyesters and polycarbonates, including the examples reported above, have been prepared using Sn‐based catalysts . Unfortunately, Sn residues can be difficult to remove during polymer purification, which may compromise the quality of the final product and the potential applicability .…”

This work presents a robust method to achieve the synthesis of low molecular weight polyesters via ring‐opening polymerization (ROP) initiated by 2‐hydroxyethyl‐methacrylate (HEMA) when using triazabicyclodecene (TBD) as catalyst. The effect that the HEMA:TBD ratio has upon the final reaction rate and final polymer molecular architecture is discussed. The optimum HEMA:TBD ratio and reaction conditions required to minimize competing transesterification reactions are determined, in order to synthesize successfully the target ROP macromonomer species containing only a single 2‐methacryloyloxyethyl end‐group. Additionally, to confirm the terminal end‐group fidelity of the product macromonomers and confirm TBD utility for block copolymer manufacture, a small series of di‐block polyesters are synthesized using TBD and shown to exhibit good control over the final polymer structure whilst negating the side transesterification reactions, irrespective of the monomers used.
