Cationic Polymerization of β‐Pinene Using B(C₆F₅)₃ as a Lewis Acid for the Synthesis of Tackifiers in Pressure Sensitive Adhesives

β ‐pinene is a well‐known bio‐based monomer that can be polymerized via cationic polymerization to give low molecular weight resins that find use commercially as tackifiers. However, the controlled synthesis of these polymers by cationic polymerization is challenging due to the reactivity of commonly used Lewis acid catalysts and the propagating carbocationic species with water. Here, the cationic polymerization of β ‐pinene under mild...
