Abstract
Surfaces are provided with desired characteristics of a polymer by covalently bonding polymer molecules to the surface through external activation of latent reactive groups carried by the polymer molecules. The initial surfaces are free of chemical groups added by surface pretreatement and which chemically participate in the covalent bonding process.
