  • Patent number: 10246548
    Abstract: The present invention relates to a composition comprising a polymeric network having at least one unit of formula (I), (II), and/or (III); wherein the composition is obtained by contacting at least one compound A comprising at least two functions selected from the group of function of formula —X—C(?O)—CHR1-C(?O)—R2, —C(?O)—C?C—R2; or —C(?O)—CR1?CR2—NR4R5; wherein at least 25% by weight of compounds A have a functionality ?5, with % by weight relative to the total weight of compounds A; with at least one compound B comprising at least one —NH2, or —NH3+ groups; wherein X, R1, R2, R3, R4, R5, L1 and L2 have the same meaning as that defined in the claims. The present invention also relates to a compound comprising at least two units and at most 5 units of formula (I), (II), and/or (III), described hereinabove.
