“…The introduction of DSCB rings, but as chain-end groups, was later reported by Delgado et al 182 Telechelic carbosiloxane and oligo(oxyethylene) polymers were thus prepared by ADMET polymerisation using silacyclobutane as chainstopper (Fig. 59).…”

Two decades have passed since the metathesis polymerisation of α,ω-dienes was successfully demonstrated by the group of Wagener and the term acyclic diene metathesis (ADMET) polymerisation was coined. Since then, the advances of metathesis chemistry have allowed to expand the scope of this versatile polymerisation reaction that nowadays finds applications in different fields, such as polymer, material, or medicinal chemistry. This critical review provides an insight into the historical aspects of ADMET and a detailed overview of the work done to date applying this versatile polymerisation reaction (221 references).

“…Drawing from the progress in highly functional polymers, using fundamental ADMET polymerization chemistry combined with various other emerging polymer developments, materials have been obtained in multiple areas including architectures of telechelic,91–94 block,80–83 crosslinked,95–97 and hyperbranched copolymers 98–101. Biological applications have also been pursued, and in addition, numerous contributions in liquid crystalline and conjugated materials have emerged with ADMET serving as the choice polymerization technique.…”

Although it is well known that Acyclic Diene METathesis (ADMET) describes an olefin metathesis polymerization mode that relies on double-bond substituent interchange of a diolefin, the story behind its discovery is not. The story is divulged here. Olefin metathesis has a rich history dating to the 1950s, but the one particular metathesis mode mentioned, ADMET, has more recent historical roots. ADMET polymerization is easy to do and highlighted here are the particular reaction details for success. Additionally, the most recent advances from the past 5 years are detailed, exemplifying this reaction's wide utility from fundamental structure-property studies to multiple advanced applications. Ken's background includes 11 years as a research chemist, research department manager, and technical director with Akzo Nobel (at American Enka in Asheville, NC), followed by his return to academics in 1984. More than 115 undergraduates, MS and PhD students, postdoctorial associates, and visiting faculty have passed through his group since then. The research group is best known for its discovery and elucidation of the ADMET reaction, now using this chemistry to precisely control structure and morphology in a large number of polymers.

“…The work related to the modification of vinylsilane monomers remained rare, although this part of work is also very important. Incorporation of some special moieties would give rise to novel monomers and derived polymers with additional interesting properties which are worth investigating 5…”

A series of benzocyclobutene (BCB) polymers derived from a new readily available monomer, 4-(1 0 ,1 0 -dimethyl-1 0 -vinyl) silylbenzocyclobutene (4-DMVSBCB), were conveniently prepared by radical and anionic polymerization. The homo-and co-polymerization results show that the reactivity of 4-DMVSBCB in anionic polymerization is relatively higher compared with radical polymerization. The molecular weight of 4-DMVSBCB polymers and content of 4-DMVSBCB can be controlled by anionic copolymerization. The introduction of rigid and crosslinkable BCB building blocks in side chains and carbosilanes in molecule gives rise to insulating materials with good film-forming property, smooth and flat film surface, and low-dielectric constants of 2.41-2.45, as preserving good thermal stability.
