ABSTRACT
Cross-linked polymer supports have been introduced in the 1940s as a result of rapidly growing research interest on solid phase synthesis, catalysis, and combinatorial chemistry. The polymerization of styrene in the presence of small amounts of divinylbenzene (DVB) as cross-linker resulted in polymer beads that showed distinctive swelling in good solvents without being totally dissolved [1]. However, the degree of swelling can easily be adjusted by varying the amount of DVB present during polymerization.
