Abstract

Single and multiple post-polymerization modifications of poly(glycidyl methacrylate) scaffold through the nucleophilic ring-opening reactions of the pendent epoxide groups are described.

Highlights

  • Poly(glycidyl methacrylate) (PGMA) is an interesting polymer

  • Post-polymerisation modification of poly(glycidyl methacrylate) (PGMA) through the nucleophilic ring opening reactions of the pendent epoxide groups allows for the installation of a variety of functionalities onto the reactive scaffold

  • This, in particular, includes reactions of the hydroxyl group(s) that come into being through the initial oxirane ring-opening reaction

Summary

Introduction

Poly(glycidyl methacrylate) (PGMA) is an interesting polymer. At rst glance, its highly strained three-membered epoxide side chains would suggest instability resulting in a short shelf-life.One could imagine that such a reactive polymer might be difficult to access synthetically especially as a homopolymer. Poly(glycidyl methacrylate) (PGMA) is an interesting polymer. PGMA can be synthesised from its commercially available and inexpensive monomer, glycidyl methacrylate, by free radical polymerization processes (Scheme 1).[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]. Stability-wise, the puri ed homopolymer can be stored at room temperature and under ambient conditions for years without compromising its structural integrity. In this way, it differs from other reactive scaffolds like alkene and alkynecarrying which can crosslink during polymerisation if the
