The invention provides an aqueous resin dispersion which can form a coating film excellent in adhesion to a polypropylene base material, and water resistance, and has excellent particle stability. Specifically, it provides an aqueous resin dispersion in which an olefin polymer (A), and a polymer (C) containing a constituent unit derived from a radically polymerizable monomer (B) represented by the following general formula (1) are dispersed in an aqueous medium. (In the general formula (1), R is a hydrogen atom or a methyl group, and X is a straight chain or branched alkylene group having 3 to 5 carbon atoms; and n is an integer of 1 to 20.)

Compositions resulting from the mixing of at least one oligomer A1, resulting from the copolymerization of at least one monomer functionalized by diol functions with at least a second monomer, and at least one compound A2 including at least two boronic ester functions. The compositions exhibit very varied rheological properties, depending on the proportion of the compounds A1 and A2 used. A composition also results from mixing at least one lubricating oil with such a composition of associative and exchangeable polymers, and to the use of this composition to lubricate a mechanical part.
