Abstract
A composition comprises polyalkylene terephthalate and terpolymer of alkylene diol, isophthalic acid and terephthalic acid, and polyalkylene terephthalate reinforcing fiber. The composition may be used to form an article, alone or with other thermoplastic material, at lower processing temperature, with higher melt flowability. The article formed is characterized with lower warpage and improved mechanical properties. The article may be useful for automotive, electrical, household, construction, and industrial applications. A method of preparing such thermoplastic polyester is also disclosed.
