Abstract
Organic polymers having water contact angles of 20° or smaller, preferably 7° or smaller and equipped with both high wettability and high transparency. The organic polymers may contain as partial structures polar structures of about 3 debyes or higher in dipole moment and are available especially from polymerization of polymerizable compounds having alkylene(thio)urea structures.
