Hayashi, Mikihiro; Obara, Haruna; Miwa, Yohei published an article in 2021, the title of the article was Design and basic properties of polyester vitrimers combined with an ionomer concept.Reference of Pentane-1,5-diol And the article contains the following content:
Vitrimers are a novel class of crosslinked materials containing associative bond exchange properties. Here we demonstrate the preparation of vitrimers with ionic components to investigate the effects of ion-rich domain formation on vitrimer properties. An amorphous polyester that bears COOH side groups was synthesized, and some fraction of COOH was neutralized with Zn2+. The residual non-neutralized COOH was reacted with diepoxy crosslinkers, resulting in a network with ester bonds, OH groups, and COOH groups neutralized with Zn2+. The sample was further thermally annealed to induce aggregation of Zn2+ ionic groups. The aggregated Zn2+ groups in the network remained active for trans-esterification-based bond exchange, wherein the degree of ion aggregation can be a factor in tuning the bond-exchange properties. The present study provides some important knowledge on the design of new mol. systems of vitrimers with tunable bond exchange properties. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Reference of Pentane-1,5-diol
