Abstract
A window assembly includes a transparent pane and an encapsulant bonded to the transparent pane, wherein the encapsulant is a copolymer of at least one amorphous thermoplastic polymer and at least one crystalline thermoplastic polymer, wherein the at least one amorphous thermoplastic polymer is at least one thermoplastic polyester, at least one thermoplastic polyether, or a copolymer of at least one thermoplastic polyester and at least one thermoplastic polyether. The at least one crystalline thermoplastic polymer may be a renewably-sourced thermoplastic polymer, wherein the total weight of the renewably-sourced thermoplastic polymer is at most 60 percent of the total weight of the copolymer.
