Abstract Sustainable bio-based monomer isobornyl methacrylate (IBOMA) was evaluated as an alternative to traditional petroleum-based methyl methacrylate (MMA) as hard monomer in the application of acrylic latex pressure sensitive adhesive (PSA). The influence of bio-based IBOMA on the viscosity and particle size of the latexes and the gel content, sol molecular weight (Mw, Mn) and adhesive properties (loop tack, peel strength and shear strength) of the PSA copolymers were investigated. In addition, transmission electron microscopy (TEM), nuclear magnetic resonance (NMR), contact angle analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA) were used to characterize the structure and properties of latexes and corresponding films. Results were compared with those obtained when using traditional petroleum-based hard monomer MMA. Some interesting phenomena and results were indeed obtained in this work. This article will not only enrich the application of bio-based monomer IBOMA in the field of acrylic emulsion PSA, but also provide sustainable methods for the preparation of high performance acrylic emulsion PSAs (e.g. high water resistance and high cohesion emulsion PSAs).

乳胶压敏胶中可持续生物基甲基丙烯酸异冰片酯替代甲基丙烯酸甲酯

摘要 可持续生物基单体甲基丙烯酸异冰片酯 (IBOMA) 被评估为替代传统石油基甲基丙烯酸甲酯 (MMA) 作为硬单体在丙烯酸乳胶压敏胶 (PSA) 的应用中。研究了生物基 IBOMA 对胶乳的粘度和粒径以及 PSA 共聚物的凝胶含量、溶胶分子量（Mw、Mn）和粘合性能（环粘性、剥离强度和剪切强度）的影响。此外，透射电子显微镜（TEM）、核磁共振（NMR）、接触角分析、差示扫描量热法（DSC）、热重分析（TGA）和动态力学分析（DMA）被用来表征乳胶的结构和性能和相应的电影。结果与使用传统石油基硬单体 MMA 时获得的结果进行了比较。在这项工作中确实获得了一些有趣的现象和结果。本文不仅丰富了生物基单体IBOMA在丙烯酸乳液PSA领域的应用，而且为制备高性能丙烯酸乳液PSA（如高耐水性和高内聚乳液PSA）提供了可持续的方法。
