Abstract: A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25 °C of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25 °C of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25 °C of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.

Abstract: A polymer matrix composite comprising a porous polymeric network; and a plurality of endothermic particles distributed within the polymeric network structure, wherein the endothermic particles are present in a range from 15 to 99 weight percent, based on the total weight of endothermic particles and the polymer (excluding any solvent); and wherein the polymer matrix composite has an endotherm of greater than 200 J/g; and methods for making the same. The polymer matrix composites are useful, for example, as a filler, thermal energy absorbers, and passive battery safety components.
