Procedure

After that, 40.0 parts by mass of behenyl acrylate was added and the polymerization was continued at 130° C. to cause chain extension with behenyl acrylate. The polymerization product was dissolved in 100.0 parts by mass of THF and taken out and dropped in methanol to reprecipitate the compound. The precipitate was then filtered and subjected to repeated washing with methanol and then to vacuum drying at 40° C. Thus, a block polymer 13 of styrene and behenyl acrylate was obtained.
