| Abstract: | Suspension-crosslinked particles of polystyrene have been prepared via a novel Friedel-Crafts reaction. Their structure and physical behaviour have been investigated using mercury porosimetry and swelling studies. The crosslinking agent used was 1,4-dichloromethyl-2,5-dimethyl benzene which exhibits limited polycondensation under the crosslinking reaction conditions. The degree of polymerization of the crosslinking agent between two crosslinks has been estimated for the crosslinked systems. The average size of the network structure has been estimated also with reference to potential g.p.c. applications. |
