These acrylates are those of formulae: <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) where R=C1-C12 alkyl, C5-C12 cycloalkyl, aryl, arylalkyl or alkylaryl; Y=C1-C12 alkyl, C6-C12 aryl, heterocyclic radical whose ring contains from 5 to 10 members and whose heteroatom is chosen from N, O and S, an alkylaryl in which the alkyl part contains from 1 to 4 carbon atoms, Y not being able to denote 1,4-phenylene when R denotes methyl; and Z=hydrocarbon radical containing at least 2 C forming with O and the 2 adjacent Cs a ring containing from 4 to 8 members. To prepare them, an acrylate of formula CH2=CH-COOR is reacted with a dialdehyde OHC-Y-CHO in the presence of an effective quantity of at least one functionalisation catalyst. The invention also relates to the preparation of new polymers and copolymers from the said acrylates.
