24 Claims

1. 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 the 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 weight CH EQW of at least 80 g/mol.
