Abstract
The invention relates to a method for the preparation of nanoparticles formed from a random polymer of at least one compound of formula (I) ##STR1## in which A represents a ##STR2## group or a ##STR3## group; R.sub.1 and R.sub.2, identical or different, represents a linear or branched C.sub.1 -C.sub.6 alkyl group; n=1, 2, 3, 4 or 5, characterised in that the monomer is dissolved beforehand in a water-miscible aprotic organic solvent forming, with the polymerisation medium, a non-solvent mixture of the polymer formed.
