Thiol‐ene Radical Coupling: A Powerful Technique for the Synthesis of Polymer Precursors, Block Copolymers and Graft Copolymers

Abstract

This chapter aims to show how reaching functional oligomers and polymers by thiol‐ene radical coupling. According to the vinyl monomers used, different strategies can be adapted in order to reach either monofunctional or telechelic oligomers. For example, combination of thiol‐ene radical coupling onto a functional monomer provides high value oligomers such as silane‐coupling agents for composite materials. This chapter also discusses thiol‐ene radical coupling onto vinyl‐containing polymers, which leads to partial modification of the properties. Finally, we showed how thiol‐ene radical coupling allows for the synthesis of block copolymers such as PMMA‐b‐PDMS‐b‐PMMA.

Biobased Amines: From Synthesis to Polymers; Present and Future

“…Thiol–ene coupling of cysteamine is one of the most famous routes to synthesize polyfunctional amines from renewable resources. Thus, a high versatility of amines could be reached. − This coupling could also be performed with an amine salt (hydrochloride cysteamine) to avoid some side-reaction, such as the addition of the amine on activated double bonds; in this case the amine function is obtained after further neutralization with a base (Scheme ).…”
