Divinyl Benzene Cross-Linked Particles
This group contains polymer which is cross-linked to produce particles which are capable of dispersion in organic solvents such as benzene or toluene. However the particle will swell in these solvents and a portion of the un-crosslinked polymer chains may be lost. When dispersed in organic solvents, the particle size will be different from that reported by T.E.M. The surface functional groups are as active as those on the un-crosslinked spheres in aqueous conditions.
DVB/Carboxyl Type ID: 14 4% solids
DVB/Sulfate Type ID: 13 4% solids
