| titleOfInvention | Species modification in macrocyclic polyester oligomers, and compositions prepared thereby |
| abstract | Physical properties, such as melting temperature of MPO compositions may be significantly modified by modifying the weight percentage of one or more of the constituent MPOs. For example, removal of a significant portion of the tetramer can afford low melting MPO compositions. In one aspect, the invention is related to a method for modifying a physical property of a MPO composition that includes the steps of (a) providing a composition that has at least two species of MPOs, and (b) changing the weight percentage of at least one species of the MPOs in the composition. In another aspect, the invention is related to a MPO composition that includes at least two species of MPOs where a species of the MPOs having the highest melting temperature is present in an amount less than or equal to 5 %. In yet another aspect, the invention is related to a MPO composition comprising 30-40 % macrocyclic polyester dimers, 30-45 % macrocyclic polyester trimers, 0-5 % macrocyclic polyester tetramers, and 5-20 % macrocyclic polyester pentamers. |
