✦ Synopsis

Abstract

A simple and efficient route for the synthesis of cyclic polymer systems is presented. Linear furan protected α‐maleimide‐ω‐cyclopentadienyl functionalized precursors (poly(methyl methacrylate) and poly(tert‐butyl acrylate)) were synthesized via atom transfer radical polymerization (ATRP) and subsequent substitution of the bromine end‐group with cyclopentadiene. Upon heating at high dilution, deprotection of the dieneophile occurs followed by an intramolecular Diels–Alder reaction yielding a high purity cyclic product. magnified image
