Macroporous ion exchange resins having increased apparent density are provided by incorporating into said resins a weighting agent which is of greater apparent density than the resin itself. Such weighted resins exhibit reduced bed expansion when used with upflow streams, with relatively dense liquids, and with relatively viscous liquids.
