N2 - Plasma polymerization of styrene, allylamine and acrylic acid was performed under nine polymerization conditions. The obtained polymers generated the film-state only under these conditions. Over 90 days, the contact angles of plasma-polymerized (pp)-films were measured on glass plates coated with pp-styrene, pp-allylamine and pp-acrylic acid. The values of the contact angles of pp-styrene, pp-allylamine and pp-acrylic acid were scattered at the initial stage under the nine polymerization conditions. However, the contact angles of these films after 40 days of storage under vacuum condition always converged into one value. These converged values of contact angles were about 87° for pp-styrene, 67° for pp-allylamine and 28° for pp-acrylic acid. We assumed that this environmental adaptability of contact angle came from the turnover of the polar functional groups between the polymer surface and bulk.
