摘要

聚烯烃（POs）是工业应用中的关键材料，开发高性能、高附加值的聚烯烃一直是一个重要而富有挑战性的研究热点。主要的挑战在于解决非极性POs和极性功能组件之间的兼容性问题。本文报道了一种基于氢化聚异戊二烯-b-聚甲基丙烯酸甘油酯(HPI-b-PGMA)/聚甲基丙烯酸甘油酯（PGMA）共混物的电子转移原子转移自由基聚合介导的聚合诱导自组装（target ATRP PISA）再生激活剂制备po基纳米物体的简单策略。动态光散射（DLS）和透射电子显微镜（TEM）显示了对稳定球形纳米物体的大范围水动力直径的有效控制。热重分析（TGA）和微尺度燃烧量热分析（MCC）表明，磷酸（H3PO4）以POs为壳，阻燃剂为核心，高效可控地引入纳米物体。本研究为制备聚苯乙烯基纳米物体提供了一条新的途径，并为聚苯乙烯基添加剂的设计开辟了一条新的途径。

Polyolefin based Nano-Objects via ARGET ATRP mediated Polymerization-Induced Self-Assembly process

Polyolefins (POs) are key materials in industrial applications, and the development of high-performance and high-value-added POs is always a significant and challenging research focus. The major challenge lies in addressing compatibility between non-polar POs and polar functional components. We herein reported a facile strategy to prepare PO-based nano-objects using an activator regenerated by electron transfer atom transfer radical polymerization mediated polymerization-induced self-assembly (ARGET ATRP PISA) process based on hydrogenated polyisoprene-b-poly (glycidyl methacrylate) (HPI-b-PGMA)/poly (glycidyl methacrylate) (PGMA) blends. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) revealed effective control over a wide range of hydrodynamic diameters of stabilized spherical nano-objects. The thermogravimetric analysis (TGA) and microscale combustion calorimetry (MCC) demonstrated the efficient and controllable introduction of phosphoric acid (H₃PO₄) into nano-objects, with POs serving as the shell and flame retardants forming the core. This work was hoped to provide a versatile route to PO-based nano-objects and open a novel avenue for designing PO-based additives.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
