Claim:
A composition comprising: a) from about 1 to about 99 wt % a thermoplastic elastomer, which is a block copolymer having at least one soft block and at least one hard block; b) from about 1 to about 70 wt % a phase change solvent having the general formula: R′—P y -(Q-P x ) n−2 -Q-P y —R; (I) R′—P y -(Q-P x ) n —R; (II) R′-(Q-P x ) n —R; (III) R′-(Q-P x ) n−1 -Q-P y —R; (IV) R′-(Q-P x ) n−1 -Q-R; or (V) mixtures thereof; (VI) wherein Q is a para-ring substituted difunctional aromatic moiety, and wherein the substitutions are in the 1,4 positions; P is CH 2 ; R and R′ are the same or different and are independently selected from H, CH 3 , COOH, CONHR 1 , CONR 1 R 2 , NHR 3 , NR 3 R 4 , hydroxyl, or C1-C30 alkoxy; wherein R 1 , R 2 , R 3 and R 4 are the same or different and are independently selected from H or linear or branched alkyl from C1-C30; x is an integer from 1 to 30; y is an integer from 1 to 30; and n is an integer from 3 to 7; wherein the phase change solvent has a phase change in a temperature range from about 40° C. to about 250° C.
