More Information
Summary:A process for modifying the surface of a polymeric substrate is disclosed, wherein said process is comprised of contacting a surface of a polymeric substrate with a protic liquid or fluid containing a diazonium composition under such conditions that will effectively allow the reaction of the diazonium composition with the surface, resulting in the attachment of aromatic groups to the polymeric surface. The polymeric substrate contains aliphatic carbon-hydrogen bonds, while the protic composition is comprised of a diazonium complex formed by diazotizing an amino compound comprised of at least one amino group bonded to an aromatic group. Also disclosed are the products generated using the aforementioned surface modifications.
