  • Stimulateable Polymer Particles Exhibiting Reactive Functions, Method for the Production and the Use Thereof
    Publication number: 20090123555
    Abstract: The invention relates to spherical particles formed by polymer chains containing approximately from 30 to 10000 monomer units derived from monocyclic polycyclic alkene polymerization, wherein at least one monomer unit is substituted by an R chain including ethylene polyoxide which is optionally covalently linked to the polymer units through a hydrolyzable bridge and substituted by a reactive function, optionally engaged in a link with an active principle or a biological molecule such as protein, wherein the chain R is covalently linked to the monomer units. The use of the inventive spherical particles for preparing pharmaceutical and cosmetic compositions or surface coatings is also disclosed.

  • Bioactive Biomaterials for Controlled Delivery of Active Principles
    Publication number: 20080004398
    Abstract: The invention relates to biomaterials comprising a carrier material to which surface spherical particles are covalently linked, wherein said spherical particles are formed by polymer chains containing approximately from 30 to 10000 monomer units derived from monocyclic polycyclic alkene polymerisation, are substituted by an R chain comprising ethylene polyoxide which is optionally covalently linked to said polymer units through a hydrolysable bridge and substituted by a reactive function engaged in a link with an active principle, said chain R being covalently linked to said monomer units. The use of the inventive biomaterials for preparing pharmaceutical and cosmetic compositions or surface coatings is also disclosed.
