Abstract
Some embodiments of the present disclosure relate to a method comprising obtaining a mixture comprising at least one vinyl polymer, at least one organic acid, and at least one hydronium ion donor. In some embodiments, the method comprises reacting an —OH group of the B polymer chain segment with the at least one organic acid in the presence of the at least one hydronium ion donor, so as to form at least one polyvinyl ester. Some embodiments of the present disclosure relate to a roofing material comprising at least one reinforcement material and at least one polyvinyl ester.
