Olefin metathesis meets rubber chemistry and technology

Abstract

This article summarizes possible applications of olefin metathesis in rubber chemistry and technology. There are three main research directives with valuable contributions to the synthesis, recycling, and characterization of elastomers. First, ring opening metathesis polymerization as well as acyclic diene metathesis polycondensation yields polyalkenamers with cross-linkable double bonds, and thus can be used for the synthesis of defined rubbers serving as raw materials in rubber technology. Secondly, by cross metathesis reaction, natural rubber (and synthetic rubber) can be functionalized resulting in telechelic polymers or small molecule specialty chemicals. Thirdly, olefin metathesis offers the possibility of degrading the cross-linked rubber network into smaller soluble pieces, enabling different analytical possibilities such as characterization of cross-linking sites, determination of rubber, rubber additives and carbon black, and exploration of the rubber-metal adhesive interface. Additionally, this route can also be used for recycling of rubber products. Graphical abstract

The Future of Ethenolysis in Biobased Chemistry

“…The versatility of the catalysis is underlined by the range of topics in recent reviews . In the field of polymer chemistry, metathesis plays an important role in the synthesis of polymers and is also applied to analyse polymers by breaking the polymer down into small, soluble parts . Metathesis catalysts have been developed to also enable the selective formation of Z‐olefins via cross metathesis.…”

Pengoptimuman Parameter untuk Penurunan Diimida Getah Asli Cecair dalam Sistem Hidrazin Hidrat/Hidrogen Peroksida Menggunakan Kaedah Rangsangan Permukaan (RSM)

“…Polimer baharu dengan ciri-ciri ketahanan sifat fizikal dan kimia yang ditingkatkan banyak dihasilkan menggunakan kaedah pengubahsuaian secara kimia (Leimgruber & Trimmel 2015). Polimer tidak tepu selalunya diubah suai kerana kehadiran ikatan karbon ganda dua yang boleh dimanipulasikan untuk membentuk struktur baru melalui beberapa siri tindak balas kimia (Fainleib et al 2013).…”

Olefin metathesis and related chemistry

“…Astrid C. Knall et al reviewed the topic of incorporating dyes into olefin metathesis polymerizationderived macromolecules and the applications of the resulting materials [11]. And finally, Simon Leimgruber and Gregor Trimmel provided a review on all aspects of olefin metathesis in rubber chemistry and technology, a field which has a long-lasting tradition at Graz University of Technology (vide supra) [12]. The reviews are complemented by six research papers.…”
