A thermoplastic membrane comprising at least one layer, wherein the at least one layer includes a first thermoplastic polymer and a second polymer having at least one isocyanate-reactive substituent dispersed within said first thermoplastic polymer.

Some embodiments of the present disclosure relate roofing membranes that may include at least one first layer including a first plurality of protrusions; at least one second layer including a second plurality of protrusions; and a plurality of inner regions disposed between a raised protrusion of the first plurality of protrusions and a raised protrusion of the second plurality of protrusions. Some embodiments of the present disclosure relate to methods of forming roofing membranes. The methods may include applying a blowable ink onto at least one porous layer; sandwiching the at least one porous layer between the at least one first layer and the at least one second layer; and expanding the blowable ink, so as to form the first plurality of protrusions, the second plurality of protrusions, and the plurality of inner regions.

A thermoplastic roofing membrane comprising a planar thermoplastic sheet, optionally having more than one layer, where at least one layer of the membrane includes an ethylene-based olefinic block copolymer, and where the sheet is characterized by a storage modulus of less than 450 MPa at 0° C.
