Polymethylene-based copolymers by polyhomologation or by its combination with controlled/living and living polymerizations

Abstract

Polyhomologation, recently developed by Shea, is a borane-initiated living polymerization of ylides leading to linear polymethylenes (C1 polymerization) with controlled molecular weight, low polydispersity, and well-defined structures. In this Review, the copolyhomologation of different ylides as well as the combination of polyhomologation with controlled/living (nitroxide-mediated, atom transfer radical, reversible addition-fragmentation chain-transfer) and living (ring opening, anionic) polymerizations is discussed.

Keywords: controlled/living and living polymerizations; polyhomologation; polymethylene-based copolymers.
