The invention relates to an RMA crosslinkable polymer comprising: a) at least one RMA Donor moiety X comprising a C—H acidic proton in activated methylene or methine groups, b) at least one moiety Y comprising one or more 5- or 6-membered heterocycles containing an ether-, acetal- or ketal group which in case of two or more of such heterocycles can be fused or linked, wherein the polymer has a weight-average molecular weight Mw of at least 400 g/mol and a C—H equivalent molecular weight CH EQW of at least 80 g/mol. The invention also relates to a process for the preparation of the RMA crosslinkable polymer, to an RMA crosslinkable composition comprising the RMA crosslinkable polymer and coated substrates.
