Procedure
A stainless steel autoclave was charged with 100 parts of a mixed solvent composed of acetonitrile and methanol (mixing ratio=50 parts/50 parts; hereinafter the same shall apply) and, after substitution of nitrogen gas for the autoclave inside atmosphere, the contents were heated to a temperature of 100° C. under pressure and tight closure. Then, a monomer mixture composed of 70 parts of styrene and 18 parts of vinylnaphthalene and a solution of 10 parts of a carboxyl group-terminated polymerization initiator [product name: V501, product of Wako Pure Chemical Industries; hereinafter the same shall apply] in 100 parts of the acetonitrile/methanol mixed solvent were added dropwise simultaneously over 1 hour and, then, the whole mixture was stirred at 100° C. for 1 hour. Thereafter, the solvent was distilled off under reduced pressure to give 95 parts of a styrene-vinylnaphthalene copolymer (a-1). The Mn of (a-1) was 1,730, the volume resistivity thereof was 8×1014 Ω·cm, and the refractive index thereof was 1.657.
