Abstract
The present invention provides a process for producing a crosslinkable styrene or styrene derivative polymer having narrow molecular weight distribution by radical polymerization of a styrene or styrene derivative monomer and other comonomer, wherein the polymerization is conducted in the presence of a catalyst system composed of a free radical compound and a radical polymerization initiator. With the present process, a heat- or photo-crosslinkable styrene or styrene derivative polymer having excellent rheology controlling ability and excellent reaction efficiency of a functional group can be obtained.
