The first part used N,N-dimethylacrylamide (DMAA) and methyl methacrylate (MMA) to replace the chain extender in polyurethane synthesis as end-capping agent to synthesize thermoplastic polyurethane (TPU) adhesive. The molecular weight of the TPU is controlled to further influence the mechanical and processing properties of the polyurethane. Here, polytetramethylene ether glycol (PTMG) and 4,4-methylene diphenyl diisocyanate (MDI) were polymerized, and then a blocking agent was added thereto. The results show that the characteristic peaks of benzene ring and carbamate of TPU adhesive are at 1596 cm\u22121 and 1413 cm\u22121, respectively, while the characteristic peaks of DMAA are at 1644 cm\u22121 and 1642 cm\u22121 in the FT-IR spectrum. There is an absorption peak \u2013N=C=O\u2013 which is not shown near 2268 cm\u22121, which proves that the structure of TPU contains the molecular structure of capping agent, PTMG and MDI. When the DMAA concentration in the capping agent was increased from 3.0 wt% to 10 wt%, the \u2013C=O (H-bond) area percentage of hydrogen bonds formed at 1711 cm\u22121 increased from 41.7% to 57.6%, while the \u2013NH (H bond) produced at 3330 cm\u22121 increased from 70% to 81%. These phenomena suggest that increasing the concentration of DMAA capping agent can effectively promote the formation of complex supramolecular network structures by hydrogen bonding in TPU. The content and concentration of the capping agent affects the molecular weight of the TPU. Chain growth is terminated when molecular weight growth can be effectively controlled and reduced. It was observed in thermal analysis that with increasing DMAA concentration in the molecular structure, the concentration of capping agent in TPU, hydrogen bonding force between hard segments, melting point (Tmh) and melting enthalpy (\u0394H) all increased the capping agent. The pyrolysis temperature of TPU is increased by 10\u201320 \u00b0C.<\/jats:p>","DOI":"10.3390\/polym14194079","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T22:53:19Z","timestamp":1664405599000},"page":"4079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Design of Acrylate-Terminated Polyurethane for Nylon Seamless Bonding Fabric Part I: Design of the End-Capping Thermoplastic Polyurethane Adhesive with Acrylate Copolymer"],"prefix":"10.3390","volume":"14","author":[{"given":"Jiong-Bo","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheng-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9157-133X","authenticated-orcid":false,"given":"Naveed","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9025-8755","authenticated-orcid":false,"given":"Chung-Feng Jeffrey","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Taiwan University of Science and Technology, Taipei 10607, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.3390\/polym9010026","article-title":"Fast-responding bio-based shape memory thermoplastic polyurethanes","volume":"121","author":"Zhang","year":"2017","journal-title":"Polymer"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1016\/j.matdes.2017.04.056","article-title":"Post-crosslinkable biodegradable thermoplastic polyurethanes: Synthesis, and thermal, mechanical, and degradation properties","volume":"127","author":"Mi","year":"2017","journal-title":"Mater.
