Abstract: The present disclosure relates to a curable precursor of an adhesive composition, the curable precursor comprising: (a) a radically (co) polymerizable (meth)acrylate-based component comprising (i) C1-C32 (meth)acrylic acid ester monomers; and (ii) an ethylenically unsaturated acidic compound; (b) a crosslinker for the (meth)acrylate-based component, which comprises at least one acid-functional group derived from phosphoric acid and at least one radically (co)polymerizable reactive group; and (c) a nitroxide wherein the C1-C32 (meth)acrylic acid ester monomers (a)(i) do not comprise functional groups other than the (meth)acrylic acid ester groups, and wherein the ethylenically unsaturated acidic compound (a)(ii) does not comprise an acid-functional group derived from phosphoric acid. The present disclosure further relates to a process for making a cured composition from said curable precursor and to the use of said curable precursor for adhesive applications and/or for thermal management applications in the automotive industry.
