Synthesis of mdh-polymer hybrid particles

Organic/inorganic hybrid particles including magnesium hydroxide cores and tethered copolymer chains are prepared. The magnesium hydroxide (MDH) particle includes attached (co)polymer chains, with the Mn/Mw of the tethered chains less than 2.0. For preparing the MDH composite, a controlled radical (co)polymerization is conducted from attached initiator functionality. The controlled radical (co)polymerization is a NMP, RAFT/MADIX or ATRP reaction. In the ATRP, the ligand is selected to allow separation of the catalyst complex from the MDH composite after the reaction is complete by dissolution in the solvent/reactants or an added solvent. For a polymer blend or alloy, the MDH composite is dispersed in an added plastic material. For preparing the composite MDH particle, the polymerization is conducted in a slurry or dispersion. The first MDH particles are functionalized by conducting an esterification reaction with a molecule additionally including a functional group to initiate a polymerization reaction.
