PROCESS FOR THE PREPARATION OF A NOVEL CROSS LINKED POLYSTYRENE RESIN HAVING DIETHYL MALONATE FUNCTIONALITY

摘要

A process for the preparation of a novel crosslinked polystyrene resin having diethy1 malonate functionality of the structure as shown in Figure 1 of the accompanying drawings where -CH - CH2 represents the  (crosslinked) polyraer backbone which comprises the steps of chloro-methylation in a known manner of a crosslinked polystyrene resin followed by reacting the chloromethylated resin with diethyl malonate as shown in Figure 2 of the drawings in the presence of a base and an organic solvent.
