Aqueous dispersions of crystalline polymers based on hydrophobic monomers, preferably on a mixture of hydrophobic and hydrophilic monomers which contains a crosslinking monomer, particularly side chain crystalline (SCC) polymers. The dispersions are useful for providing coatings on substrates, particularly on seeds (whose dormancy is thus extended) and on fibrous substrates, particularly human hair (which thus becomes heat-settable).

L'invention porte sur des dispersions aqueuses de polymères cristallins à base de monomères hydrophobes et de préférence à base d'un mélange de monomères hydrophobes et hydrophiles contenant un monomère réticulant. Lesdits polymères sont en particulier du type à chaîne latérale cristalline (SCC). Ces dispersions servent à déposer des revêtements sur des substrats, en particulier sur des graines (dont la dormance peut ainsi être prolongée), ou sur des substrats fibreux, et en particulier sur des cheveux humains (qu'on peut ainsi traiter à chaud).
