ABOUT 20 TO 95 WT. PERCENT OF A POLYESTER WHEREIN ABOUT 5 TO 20 MOLE PERCENT OF THE DICARBOXYLIC ACID COMPONENT COMPRISES AN ALIPHATIC DICARBOXYLIC ACID, THE POLYESTER HAVING A MELTING POINT OF OVER ABOUT 150 DEG C, and B. ABOUT 5 TO 80 WT. PERCENT OF A POLYESTER WHEREIN ABOUT 25 TO 35 MOLE PERCENT OF THE DICARBOXYLIC ACID COMPONENT COMPRISES AN ALIPHATIC DICARBOXYLIC ACID, THE POLYESTER HAVING A MELTING POINT BETWEEN ABOUT 50 AND 150 DEG C.
