Consequently, adipoyl chloride condensed on the surface of the base particles. A polymerization reaction, using as a catalyst triethylamine contained in the base particles, took place between adipoyl chloride condensed on the surface of the base particles and 1,6-hexanediol contained therein, forming a film of 1,6-hexanediol-adipoyl chloride co-polymer on the surface of the base particles.
