Abstract
The present invention provides a polymer complex of a sugar response type having boronic acid groups in the polymer. Medicines may be contained or linked, preferably, the medicines have hydroxy groups. The polymer having boronic acid groups and the medicine having hydroxy groups may be linked by boronic acid ester bonds. The complex may also comprises polymers having boronic acid groups and polymers having hydroxy groups, and these polymers may be cross-linked.
