Abstract:
A method of making an optical laminate, comprising the steps:a) extruding an interlayer film from a blend of at least one linear low density polyolefin having a density from about 0.850 to 0.905 g/ccm, a polydispersity index of less than 3.5, and less than 20%, by weight, crystallinity; a coupling agent in an amount of from about 0.2% to about 2.0% by weight of a total formulation; a nucleation agent in an amount of from about 0.05% to about 2.0% by weight of the total formulation; a crosslinking agent in the amount of from about 0.05% to about 2% by weight of the total formulation; b) incorporating the interlayer film between at least two sheets of material selected from the group consisting of mineral glass, polymer glass and combinations thereof; and c) adhering the interlayer film to the sheets of material to form an optical laminate, wherein the optical laminate has a haze value of less than 4% at a film thickness of 125 to 1,000 mcm.
