  • Methylidene malonate nanoparticles
    Patent number: 6420468
    Abstract: Nanoparticles formed from a random polymer of at least one compound of formula (I) in which A represents a group or a group; R1 and R2, identical or different, represent a linear or branched C1-C6 alkyl group; n=1, 2, 3, 4 or 5, having a diameter of less than 500 nm and an average molecular mass (Mw) between about 8000 and 100000, the nanoparticles being formed from homogeneous molecular species, and optionally containing a biologically active material.

  • Method for preparing malonate methylidene nanoparticles, nanoparticles optionally containing one or several biologically active molecules
    Patent number: 6211273
    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) in which A represents a  group or a  group; R1 and R2, identical or different, represents a linear or branched C1-C6 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.
