Films and articles made with thermoplastic block copolymers

A cured in place liner for a passageway or pipe comprising:

• (a) a resin absorbent material layer;
• (b) a thermoset resin absorbed into said resin absorbent material layer;
• and (c) a TBC coating layer on at least one side of said resin absorbent material layer;
• wherein the TBC is comprised of (I) the reaction product of (1) a hydrophobic polyol or polyamine, (2) a polyisocyanate or an aromatic dicarboxylic acid, and (3) a linear chain extender containing 2 to 20 carbon atoms, or (II) the reaction product of (1) a hydrophobic polyol or polyamine, and (2) a carboxyl terminated telechelic polyamide sequence;
• wherein the hydrophobic polyol or polyamine has a number average molecular weight which is within the range of about 1,000 to about 4,000 Daltons;
• wherein the TBC has a weight average molecular weight which is within the range of 50,000 to 1,000,000 Daltons;
• and wherein the TBC has a melting point which is within the range of 80° C. to 250° C.
