Abstract
In a first aspect, a multilayer polymer film includes a first polymer layer having a first elastic modulus and a second polymer layer having a second elastic modulus. The first polymer layer includes a polyimide, a polyamide imide, a block copolymer of a polyimide or a polyamide imide or a mixture thereof. The second polymer layer includes a polyimide, a polyamide imide, a block copolymer of a polyimide or a polyamide imide or a mixture thereof. The first elastic modulus is different from the second elastic modulus. The first and second polymer layers are bonded by consolidation. In a second aspect, a cover window for a display includes a hard coat layer and the multilayer polymer film of the first aspect. The first polymer layer of the multilayer polymer film is the layer farthest from the display and is adhered to the hard coat layer.
