Inventor(s): Shangxin Jiang, Isabella Luisi and Sigrun Clement
Company: REBAC GmbH
Patented is composite material comprising a microparticle support consisting essentially of polymeric organic particles. Metallic and non-metallic ions are grafted to the surface of the support. The particles are a copolymer of at least three monomer units. The first monomer unit has the formula: R1, R2 and R3, which are independently selected from the group consisting of hydrogen, a C1-3 alkyl group and a halogenated C1-3 alkyl group. The monomer has either an E or Z configuration. The second monomer unit is selected from the group consisting of C1-3 alkyl esters of acrylic acid, methacrylic acid and crotonic acid. The third monomer unit is an ethylenically unsaturated monomer with at least one acid group.
