摘要:
A method for increasing the crystallization rate of a crystallization polyester comprises incorporating into the polyester an effective amount of a hyperfunctional nucleation agent. The hyperfunctional nucleating agent comprises a plurality of functional groups and form stable nuclei around which the polyester crystallizes. The hyperfunctional nucleating agent facilitates faster crystallization and formation of many small crystallites. Methods of making articles such as containers with polyesters are also disclosed.
