Abstract
The present invention is directed to a particle-containing entity P-(A--B-M)wherein P is a solid particle attached to at least one polymer M through one or several reversible covalent bonds -A---B-, wherein A and B are functional groups respectively grafted to P and M thus forming the P-(A---B-M)particle-containing entity with x being greater than or equal to 1, M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500, and wherein the reversible covalent bond -A---B- is chosen among an imine, a disulfide, a boronic ester or an acetal. The invention is also directed to a method of preparing this particle-containing entity, a method for sequentially forming and breaking the reversible covalent bond -A---B- in said particle-containing entity P-(A---B-M)and dispersions comprising same.
