The aggregation of poly(ε-caprolactone) containing different number of carboxyl groups at one chain end in the presence of Ca2+ cations was investigated by viscosity measurements. With increasing number of carboxyl groups, aggregation is strongly enhanced as evidenced by the viscosity-time profiles. The formation of long cylindrical structures was observed by scanning electron microscopy.
