FREE-RADICAL CURABLE COMPOSITIONS

摘要

Free-radical curable compositions contain: (1) a reactant having a non-polyester saturated backbone and an average of at least one electron deficient ethylenically unsaturated end group per molecule of saturated reactant; and (2) at least one of a single functional diluent and a dual functional monomer wherein the ratio of electron-rich double bonds to electron-deficient double bonds in the compositions is in the range of about 5:1 to about 1:5. The compositions can further comprise an oligomer having an average of at least one electron-rich ethylenically unsaturated group per molecule of oligomer. The compositions are useful as coatings for various substrates and optical glass fibers.
