Carboxyl End Groups In PET Chips

Polyethylene terephthalate (PET) is synthesized through the condensation of terephthalic acid (PTA) and ethylene glycol (EG). Its molecular backbone comprises rigid benzene rings and flexible alcohols, making it a saturated linear polymer. PET is a milky white or light yellow, highly crystalline polymer with a smooth, glossy surface. It boasts excellent physical and mechanical properties
