The supplier does not provide the molecular weight or a molecular weight range for any of the latex beads. Polystyrene has a linear formula of [CH2CH(C6H5)]n. There are no exact values for the molecular weight available, although some internet sources may state a range of 100,000 to 400,000 amu. The polystyrene can be unmodified or surface modified. The dye is encapsulated inside the surface functionalized (amine or carboxylic) PS beads, which are well dispersed in the cationic surfactant assisted solution. The dye is not strongly bonded, and the PS may have a porous structure, so the dye can come out when changing to an organic solvent.

Hi, can you please provide me some information about the density of amines loaded on the surface of this particles?
1 answer-
The amine content is not specifically quantified on a lot-to-lot basis. Historical data indicate a total parking area of 30 to 300 angstroms squared per charge group. Unfortunately, no further information is available.
