This is done by using a simple synthetic approach which utilizes click hemistry. Temperature-dependent dynamic mechanical properties are studied, and it turns out that even the apparently rather simple ydrogen bonding motif has a marked impact on the material properties due to the fact that it facilitates the formation of a supramolecular polymer network. Besides a glass transition, the investigated functionalized copolymers exhibit a second endothermic transition, known as a quasi-melting. This is related to the opening of the hydrogen bonding complexes. Additionally to dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), temperature-dependent infrared (IR) spectroscopy and small angle X-ray scattering (SAXS) are used to understand the structure-property relationships.en1744-683X20181427012711https://creativecommons.org/licenses/by-nc/3.0/IngenieurwissenschaftenJournal Articleurn:nbn:de:gbv:830-8822036810.15480/882.162511420/162810.1039/C8SM00296G10.15480/882.1625Other
