Abstract
This invention relates to certain poly(1,4-cyclohexylenedimethylene terephthalate) copolyesters which are useful for the preparation of clear and tough thick wall molded parts, produced at good cycle times. The copolyesters can be molded into desired shapes such as cosmetic jars, fragrance caps, tool handles, and toothbrushes. These molded articles can have thick or thin walls and may be molded in a two shot molding process. The copolyesters also have good flow and reduced cycle times.
