This contribution describes our recent efforts geared toward the use of a general, thio-bromo "click" reaction as a post-polymerization method for the preparation of flameresistant polymeric materials. a-bromo ester-containing polymers could easily be prepared using ROMP and a subsequent, facile thio-bromo click reaction was used for the installation of a phosphorus-moiety that was shown to impart flame-resistant/self-extinguishing properties to these polymers. The extent of their flame resistance was then ascertained by treating paper (previously coated with polymer) to standard burn tests as well as measuring the limiting oxygen index (LOI).

The preparation of functionalized graft copolymers utilizing a combination of ATRP, ROMP, thio‐bromo, and Huisgen‐type click chemistries is described. The construction of these polymeric architectures hinges on the use of a norbornene‐based α‐bromo ester that can act as an ATRP initiator and ROMP monomer (a so‐called inimer), as well as a thio‐bromo click partner. This allows for the use of a “grafting‐through” ROMP approach of ATRP‐based macromonomers that can undergo a post‐polymerization thio‐bromo click modification. Additionally, this material can undergo further modifications using archetypal copper‐catalyzed azide/alkyne click reaction as well as metal‐free strain‐promoted azide/alkyne click reactions.
