Reverse gear : Additions of primary radicals to sterically non‐congested vinyl bonds may indeed not be as irreversible as commonly assumed. A 1 H‐CIDNP NMR spectroscopic investigation on photoinitiated polymerization systems provides evidence that the addition of photolytically generated mesitoyl and phosphinoyl radicals to (meth)acrylate monomers at ambient temperatures may be reversible (see scheme; I =initiator).
