Abstract

A bond is produced between a synthetic polymer containing vicinal hydroxyl groups and a substance containing primary amino groups by treating the polymer with a medium to strong oxidant until a sufficient number of aldehyde groups is formed and then reacting the oxidation product with the substance containing primary amino groups.
