Patent number: 6900252Abstract: There is provided a radiation-curable coating or packaging composition containing vinyl acrylate and one or more additional components, wherein the composition does not contain a photoinitiator, and the composition polymerizes upon irradiation. The irradiation forms a polymer that demonstrates thermal stability and abrasion resistance, and functions as a moisture barrier.

A feature of the invention is that the polymerization through exposure to radiation of a composition containing vinyl acrylate may also initiate the polymerization of one or more of the additional components within the composition that would not ordinarily polymerize in the absence of a photoinitiator.Type: GrantFiled: December 11, 2001Date of Patent: May 31, 2005Assignee: AlcatelInventors: Igor Vladimir Khudyakov, Charles Ensley Hoyle

Patent number: 6869983Abstract: An in situ polymer microstructure formation method.
