  • Method for Obtaining Functionalised Polymer Particles
    Publication number: 20210032416
    Abstract: The present invention relates to a precipitation polymerization method for obtaining spherical polymer particles of a copolymer with statistical topology and chemical structure (acid monomer selected from acrylic or methacrylic)-co-(cross-linker selected from acrylic or methacrylic)-co-(hydroxylated monomer selected from acrylic or methacrylic) and which are functionalised with a divalent cation selected from Zn+2, Ca+2, Mg+2 and Sr+2 and/or an antibacterial agent. The invention also relates to said polymeric particles. The invention further relates to a composition comprising the polymeric particles and to the use of the particles to produce a drug.
