CROSS-LINKED POLYMERIC BEADS WITH UNIFORM SHAPE AND SIZE

摘要

Provided is a crosslinked polymer bead which has very uniform shape and size, is gel type or porous by preparing the crosslinked polymer bead by using a piped reactor, and is reduced in the discharge of waste. A crosslinked polymer bead is prepared by supplying a reactant comprising a monovinyl monomer, a crosslinking monomer and a catalyst and a carrier fluid phase separated from the reactant into the entrance of a reactor tube so as to allow them to be repeatedly branched and flow in the flow direction of the reactor pipe; converting the reactant into a polymer bead by polymerization during the retention period passing the reactor tube, and discharging the polymer bead and the carrier fluid at the exit of the reactor tube in turn, and has a shape of sphere, eclipse and rod and an average diameter of axis of 1-50 mm.
