Patent ID: 10836899

Abstract:
A semi-crystalline polyester comprising a repeat unit of the formula: wherein A is an aliphatic, aromatic, or heterocyclic group; R1 is selected from the group consisting of 1,4-butanediol residue and 1,4-cyclohexanedimethanol residue; R2 is neopentanediol residue; m is between 50 and 99 inclusive; n is between 1 and 50 inclusive; x is between 1 and 200 inclusive; and wherein said semi-crystalline polyester exhibits a minimum crystallization half-time of about 0.3 minutes or greater, or about 0.5 minutes or greater or about 0.6 minutes or greater or about 0.7 minutes or greater is described. The polyesters of the present invention may in various embodiments demonstrate one or more desirable performance characteristics and accordingly are particularly useful in applications and utilities wherein those high levels of performance for such characteristics are required. A process for forming the semi-crystalline polyester is also disclosed.
