Abstract: A polymer composition includes: a first proportion of an aliphatic-diisocyanate terminated polyol; a second proportion of an aromatic diisocyanate; a third proportion of an aromatic diamine curative configured to extend a chain length of the aliphatic-diisocyanate-terminated polyol and the aromatic diisocyanate; a fourth proportion of a polyester polyol configured to polymerize with the aliphatic-diisocyanate-terminated polyol; and a fifth proportion of a high functionality dendrimer configured to crosslink polymer chains of the aliphatic-diisocyanate-terminated polyol. Further, the hybrid copolymer can be configured to form a protective film layer in a foldable electronic display, the foldable electronic display including: a cover layer arranged over the protective film layer; and an array of organic light-emitting diodes arranged beneath the protective film layer.
