International Classification:

C08L 67/02
C08G 63/183

US Classification:

524605, 528193

Abstract:

A polyester containing polymerized units of hydroquinone; 4,4′-biphenol; and hydroxybenzoic acid; terephthalic acid and optionally isophthalic acid. A method of forming a polyester including first acylating a mixture of hydroquinone; 4,4′-biphenol; terephthalic acid and optionally isophthalic acid; and hydroxybenzoic acid; and then polycondensing the resulting acylated mixture. The polyester is suitable for uses such as lighting where high whiteness, high reflectivity and high heat resistance are desirable.
