Patent ID: 7563838

Claim:
A composition comprising: a) from 1 to 99 wt % of a thermoplastic polymer selected from the group consisting of a polyester, a polyamide, a polyether, a polyurethane, a polycarbonate, a vinyl polymer, a copolymer and a mixture thereof; and b) from 1 to 70 wt % of a phase change solvent characterized by an AA ratio, wherein the phase change solvent has the general formula: R′—P y -(Q-P x ) n-1 -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-a) R′-(Q-P x ) n-1 -Q-R; or (IV-b) a mixture thereof; wherein Q is an unsubstituted or unsubstituted difunctional aromatic moiety; P is CH 2 ; R and R′ are the same or different and are independently selected from the group consisting of H, CH 3 , COOH, CONHR 1 , CONR 1 R 2 , NHR 3 , NR 3 R 4 , hydroxy, and 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; x and y are independently an integer from 1 to 30 and x does not equal y; 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.
