Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus
AIChE Journal, EarlyView.Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

Adhesion to Untreated Polyethylene and Polypropylene by Needle-like Polyolefin Crystals
, 2023 Polyolefins, such as polyethylene and polypropylene, are globally the most widely used plastics and are considered to be essential materials. Because they lack polar groups, polyolefins are poorly adhesive, which poses serious recycling challenges. Here,
