Abstract (en)
[origin: WO2004039854A2] The invention concerns a macroporous material in the form of plastic pearls, having an average particle diameter ranging between 10 and 1000 mu m, containing a copolymer consisting of: a) 5 to 60 wt. % of monomers capable of being subjected to vinyl polymerization, being at least 1 % water soluble at 20 DEG C; b) 1 to 40 wt. % of monomers capable of being subjected to vinyl polymerization, comprising an additional functional group capable of being covalently bound to nucleophilic groups of ligands, during a polymerization-like reaction; c) 10 to 40 wt. % of hydrophilic monomers capable of being subjected to a crosslinking free radical polymerization, comprising at least two ethylenically unsaturated polymerisable groups; and d) 10 to 60 wt. % of monomers capable of the subjected to vinyl polymerization, not more than 1 % water soluble at 20 DEG C, the sum of the monomers a) through d) being generally equal to 100 %.
