Abstract
A polymer film, polymer-coated nonwoven web, and a polymer-coated fiber formed by a process wherein an admixture of unsaturated polymerizable material and a photoreactor composition are drawn into a film or coated onto a web or fiber. The photoreactor composition includes a photoinitiator associated with a wavelength-specific sensitizer. The film, web or fiber is subsequently irradiated with light to polymerize the admixture.
Claims6
A polymer film, produced by the process of:
- providing a film comprising an admixture of unsaturated polymerizable material and a photoreactor, wherein the photoreactor is represented by one of the following formulae;
- ##STR13## irradiating the film with an amount of radiation sufficient to polymerize the admixture.
