Abstract
Boron functionalities in polymer chemistry are currently often explored in dynamically crosslinked materials, compatibilizers, adhesives, and other biological applications because of their selective and reversible esterification/condensation properties. Some applications have been investigated for polyolefin materials, which rely on postpolymerization functionalization to introduce boron functionalities.
Our recent approach enabled the direct incorporation of boronic acid functionalities via copolymerization using a newly designed comonomer applicable to versatile metal-catalyzed polymerization systems. This strategy allowed boronic acid functionalities to be incorporated into major commodity hydrocarbon-based plastics and rubbers with control over the uniform molecular weight between functional groups. Using this synthetic platform, we have developed a variety of functional materials, including boron-crosslinked elastomers and crystalline polyolefins reinforced through boron-mediated crosslinking. Here, we present another application of boron-functionalized random polypropylene (PP) and polyethylene (PE) as a compatibilizer of PP/PE blends. The covalent network formed by these copolymers at an optimized composition significantly improved the mechanical properties of the polyolefin blend.
