Abstract: Polyester pressure-sensitive adhesives are described. The polyester includes at least two different diacid residues and at least two different diol residues. The at least two different diacid residues include, based on the total moles of the at least two diacid residues, 20 to 80 mole percent of a residue of at least one aromatic dicarboxylic acid, and 20 to 80 mole percent of at least one of a residue of adipic acid or sebacic acid. The polyesters may include at least one pendant group containing an alkenyl group.

Abstract: A polyester including at least one crosslinkable moiety is described. Each crosslinkable moiety includes at least one crosslinkable pendent group. A ratio of a total number of the at least one crosslinkable pendent groups to a total number of ester groups in the polyester may be in a range of 0.0001 to 0.5.

Abstract: Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness. The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.

Abstract: A thermal management assembly comprises an electrochemical cell, a heat sink, and a thermal pathway comprising a thermally interruptible interface interposed therebetween the electrochemical cell and the heat sink. The thermal pathway comprises an expandable material comprising intumescent particles. If heated to at least a first onset temperature, the expandable material expands and causes at least partial shear delamination at the first thermally interruptible interface. A composite thermal management article comprises a first layer comprising an expandable material comprising intumescent particles and a second layer comprising a thermal conductor material. The first and second layers contact each other at a thermally interruptible interface. If heated to at least a first onset temperature, the expandable material expands and causes at least partial shear delamination at the thermally interruptible

Abstract: A substrate including a self-supporting tri-layer stack is described. The tri-layer stack includes first and second outer layers and a biaxially oriented layer disposed between and in direct contact with the first and second outer layers. The biaxially oriented layer may include a first polyester having greater than 45 mole percent naphthalate units and greater than 45 mole percent ethylene units. Each of the first and second outer layers includes a second polyester which may include 40 to 50 mole percent naphthalate units, at least 25 mole percent ethylene units, and 10 to 25 mole percent of branched or cyclic C4-C10 alkyl units.
