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 (H 3 PO 4 ) 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.
