Abstract
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.
Claims26
A process for modifying the surface of a polymeric substrate, said process comprising:
- providing a polymeric substrate containing aliphatic carbon-hydrogen bonds;
- forming a protic composition comprising a diazonium salt formed by diazotizing an amino compound comprising at least one amino group bonded to an aromatic group;
- and
- contacting a surface of said polymeric substrate with said protic composition under conditions effective to allow reaction of said composition with said surface, resulting in attachment of said aromatic group to said surface.
