<p>The present application describes a method for initial polymerization or gelling a composition of epoxy resin at a temperature of 50°C or less, over a period of 24 hours or less by the incorporation of a fluorinated carboxylic acid. The compositions used in the present invention can be gelled without the use of heat or light. The fluorinated carboxylic acid includes a carboxylic acid terminated fluoropolyether. The composition includes a cycloaliphatic epoxy resin. The invention further includes objects that comprise a polymerization product of a composition or materials prepared according to the method In addition, the present application describes the use of such materials in optical systems that include a first component, a second component, and the material disposed between the first and second optical components.</p> |
