Abstract:
Structures having an interpenetrated polymer layer are described. The interpenetrating layer (230) comprises a mixture of a first component (211) and a second component (212), wherein the concentrations of the first component and the second component vary inversely across the thickness of the interpenetrating layer. Both interpenetrated surface layers (210, 220) and interpenetrated bonding layers (230) are described. Methods of forming an interpenetrated layer are also disclosed.

Abstract:
A method of making a multilayer protective film. The method comprises: (a) forming a PU layer comprising an at least partially crosslinked polyurethane, the at least partially crosslinked polyurethane comprising at least one of a polyester-based polyurethane or a polycarbonate-based polyurethane; (b) forming a TPU layer comprising a polycaprolactone-based thermoplastic polyurethane; (c) forming a PSA layer comprising a pressure sensitive adhesive; (d) bonding one major surface of the PU layer to one major surface of the TPU layer; and (e) bonding the PSA layer to an opposite major surface of the TPU layer; wherein the TPU layer is sandwiched between the PU layer and the PSA layer. The multilayer film may be used to protect painted surfaces of vehicle body parts.
