Title
(EN) RMA CROSSLINKABLE POLYMER
(FR) POLYMÈRE RÉTICULABLE PAR RMA
Abstract
(EN)
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.
(FR)
L'invention concerne un polymère réticulable par RMA comprenant : a) au moins une fraction donneuse de RMA X comprenant un proton acide C-H dans des groupes méthylène ou méthine activés, b) au moins une fraction Y comprenant un ou plusieurs hétérocycles à 5 ou 6 chaînons contenant un groupe éther, acétal ou cétal qui, dans le cas d'au moins deux de ces hétérocycles, peuvent être fusionnés ou liés, le polymère présentant un poids moléculaire moyen en poids (Mw) au moins égal à 400 g/mol et un poids moléculaire équivalent de C-H (CH EQW) au moins égal à 80 g/mol. L'invention concerne également un procédé de préparation du polymère réticulable par RMA, une composition réticulable par RMA comprenant le polymère réticulable par RMA et des substrats revêtus.
