Patent ID: 7666517

Claim:
A process for shaping a partially-crystallized macrocyclic oligoester, the process comprising the steps of: (a) isolating a substantially solvent-free molten macrocyclic oligoester from a solution comprising macrocyclic oligoester and solvent, the macrocyclic oligoester comprising a structural repeat unit of formula (I): wherein R is an alkylene, a cycloalkylene, or a mono- or polyoxyalkylene group and A is a divalent aromatic or alicyclic group, wherein the substantially solvent-free molten macrocyclic oligoester has a solvent content of less than 200 ppm; (b) shearing the substantially solvent-free molten macrocyclic oligoester to form a partially-crystallized macrocyclic oligoester; and (c) shaping the partially-crystallized macrocyclic oligoester.
