“…Homopolymerization of 4-methyl-1-pentene Poly(4-methyl-1-pentene) is a thermoplastic resin developed a long time ago [82]. Due to its low density, superior heat resistance, UV light transmittance, excellent electrical insulation, and chemical resistance [83], it has attracted more and more interest from researchers.…”

Metallocene catalysts have attracted much attention from academia and industry for their excellent catalytic activity in the field of olefin polymerization. Cocatalysts play a key role in metallocene catalytic systems, which can not only affect the overall catalytic activity, but also have an obvious influence on the structure and properties of the polymer. Although methylaluminoxane (MAO) is currently the most widely used cocatalyst, its price increases the production cost of polyolefin materials. Ammonium tetrakis(pentafluorophenyl)borate has shown excellent performance in polymerization, being one of the best substitutes for the traditional cocatalyst MAO. Compared with the main catalyst, whose composition and structure are relatively complex, the research on cocatalyst is very limited. This review mainly introduces the research history, preparation methods, and application progress in polymerization of ammonium tetrakis(pentafluorophenyl)borate, deepening our understanding of the role of cocatalyst in polymerization, with the hope of inspiring brand-new thinking on improving and enhancing the overall performance of catalyst systems.

The trade‐off between gas permeability and resistance to plasma leakage imposes a great challenge for the practical use of membranes in extracorporeal membrane oxygenation (ECMO). Herein, a polypropylene (PP) hollow‐fiber composite membrane is fabricated by simply grafting mesoporous silica nanoparticles onto the commercial PP membrane, which shows a significantly enhanced gas permeability and superior resistance to plasma leakage. The performance metrics such as gas permeability, bubble point, surface hydrophobicity, and plasma leakage resistance are largely influenced by the type of functional groups on the silica nanoparticles (hydroxyl, vinyl, or trifluoropropyl). It is shown that the trifluoropropyl‐group functionalized mesoporous silica nanoparticle grafted composite membrane demonstrates a superior performance than the commercial ECMO membrane of poly(4‐methyl‐1‐pentene) (PMP). The bubble point is greatly elevated from 0.36 to 1.20 MPa while the decrease in gas flux is negligible within 4%. And the leakage resistance time is significantly prolonged from 600 to 4140 min. The gained benefits are originated from the enhanced mass transfer area and diminished surface pores of the composite membrane are grafted with the mesoporous nanoparticles. The high‐performance PP‐based composite membranes are cost‐effective and promising in practical applications of ECMO.
