“Films composed of polyesters within the thickness range specified are sufficiently well known. However, a disadvantage of such polyester films is their hydrolysis tendency, especially at temperatures above the glass transition temperature of the particular polyester. In this context, the hydrolysis tendency is understood to mean the property of the polyester of being degraded hydrolytically under moist conditions, which is noticeable, for example, by a reduction in the IV or SV. This is a limiting factor for the use of polyester films especially in applications with relatively high thermal stress, such as in film capacitors, cable sheathing, ribbon cables, engine protection films, but also in long-term applications such as in glazing and outdoor applications, and especially in the backside laminate of solar modules.” [Kliesch  et al, US Patent 8,277,710 (10/2/2012)]
