Abstract
A crosslinkable composition including a component A with at least 2 acidic protons C—H in activated methylene or methine groups (the RMA donor group), and a component B with at least 2 activated unsaturated groups (the RMA acceptor group), and a catalyst system C that contains, or is able to generate a basic catalyst capable of activating the RMA reaction between components A and B, characterised in that the cross-linkable composition further includes an X—H group containing component D that is also a Michael addition donor reactable with component B under the action of catalyst C, wherein X is N, P, O, S or wherein X is C as part of an acidic methyl (CH3) group. A component D and catalyst additive mixtures for the manufacture of RMA crosslinkable composition.
