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. The present invention also relates to processes for preparing the composition and the compounds, to material, articles, and polymers comprising or using the compositions and compounds, and the use thereof.
本发明涉及一种组合物,该组合物由至少具有一个式(I)、(II)和/或(III)单元的聚合物网络组成;
其中该组合物是通过与至少一种化合物A接触而获得的,该化合物A包含至少两种选自式-X-C(═O)-CHR1-C(═O)-R2,-C(═O)-C≡C-R2;或-C(═O)-CR1═CR2-NR4R5的官能团;其中至少25%(重量)的化合物A的官能度≤5,以相对于化合物A总重量的%(重量)计;至少一种化合物B包含至少一个-NH2,或-NH3+基团;其中X、R1、R2、R3、R4、R5、L1和L2与权利要求书中所定义的含义相同。本发明还涉及一种包含至少两个单元和至多 5 个单元的式(I)、(II)和/或(III)化合物。本发明还涉及制备组合物和化合物的工艺,涉及包含或使用组合物和化合物的材料、物品和聚合物及其用途。
