Abstract:
A liquid polymer precursor comprising:from about 5 to about 15 weight percent of at least one vinyl ether functionalized compound;an amount of at least one epoxy functionalized compound ranging from about 2 to about 10 times the weight of vinyl ether functionalized compound in the precursor composition;an amount of at least one acrylate functionalized compound ranging from about 2 to about 8 times the weight of vinyl ether functionalized compound in the precursor composition; andat least one photoinitiator wherein the epoxy functionalized compounds, the vinyl ether functionalized compounds and the acrylate functionalized compounds are present in the composition in an amount sufficient to ensure that upon photoinitiation, the epoxy functionalized compounds polymerize primarily by cationic chain transfer polymerization and wherein the vinyl ether functionalized compounds polymerize primarily by radical polymerization and combine with the acrylate functionalized compounds to form a copolymer.
