    摘要： The presently claimed invention comprises a biopolymer nanoparticle for drug delivery wherein the nanoparticle comprises a homogeneous blend of an aliphatic polyester polymer blended with a polyether, a lipophilic or polypeptide drug and a biocompatible cholesterol interacting agent for preserving the activity of the drug administered to the patient while at the same time controlling the release of the drug. Methods for making the homogeneous drug delivery nanoparticles are also disclosed.

    摘要： The process for the controlled radical (co)polymerization of (meth)acrylic and/or vinyl monomers is characterized in that the bulk, solution, emulsion or suspension polymerization or copolymerization is carried out, at a temperature at which can fall to 0.degree. C., of at least one of the said monomers in the presence of an initiating system comprising a radical-generating compound and at least one catalyst composed of a metal complex containing a ligand of the type�4-R.sup.3 -2,6-(CH.sub.2 NR.sup.1 R.sup.2).sub.2 C.sub.6 H.sub.2 !--(I)in which: R.sup.1 and R.sup.2, which are identical or different, represent a branched or unbranched C.sub.1 -C.sub.4 alkyl group or a phenyl group or alternatively R.sup.1 and R.sup.2 form, with the nitrogen atom to which they are connected, a cyclic amine or alternatively the two R.sup.2 groups, taken together, form a polymethylene bridge and R.sup.3 represents a hydrogen atom, an alkyl or benzyl group or an electron-donating or electron-withdrawing functional group.
