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 &#x2014;X&#x2014;C(&#x2550;O)&#x2014;CHR1-C(&#x2550;O)&#x2014;R, &#x2014;C(&#x2550;O)&#x2014;C&#x2261;C&#x2014;R; or &#x2014;C(&#x2550;O)&#x2014;CR&#x2550;CR&#x2014;NRR; wherein at least 25% by weight of compounds A have a functionality &#x2264;5, with % by weight relative to the total weight of compounds A; with at least one compound B comprising at least one &#x2014;NH, or &#x2014;NHgroups; wherein X, R, R, R, R, R, Land Lhave 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.

Compositions comprising a polymeric network

The present invention is directed to an entity comprising a particle attached to at least one polymer M through one or several supramolecular interactions -A-B- constituted by 2 to 8 hydrogen bonds X-H-Y, wherein A and B are functional groups respectively grafted to P and M thus forming the particle-containing entity P-(A-B-M)x with x being greater than or equal to 1, functional group(s) B being positioned at one end of the polymeric chain of polymer M, X and Y are heteroatoms present in A and B functional groups, H is hydrogen, and M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500. The invention is also directed to a method for preparing this particle-containing entity P-(A-B-M), a method for sequentially forming and breaking the supramolecular interactions -A-B- in said particle-containing entity P-(A-B-M)and dispersions comprising the same.
