Abstract
A composition and a method for manufacturing the composition are provided that includes a thermoplastic polyurethane (TPU) and a second component in an amount in the range of about 3% to about 60% by weight of the composition. The second component includes at least one reactive diluent, monomer, or oligomer (RDMO). The RDMO and/or the TPU may be cross-linked to form a semi-interpenetrating polymer network or an interpenetrating polymer network. The RDMO provides improved physical properties, such as rigidity, durability and strength, to the TPU. The polymer network may be bonded to other layers for certain applications, such as windows and flooring, to improve flexibility and strength, inhibit shattering and/or resist scratching and staining.
