Isoconversional Glass Transition Kinetics and Fragility Determination of Poly[(ethylene 2,6-naphthalate)-co-(butylene 2,6-naphthalate)] Random Copolymers (original) (raw)

This study investigates the glass transition kinetics and fragility of poly[(ethylene 2,6-naphthalate)-co-(butylene 2,6-naphthalate)] random copolymers through isoconversional techniques. It explores the variation of activation energy during the glass transition based on the sequence composition, revealing that increased butylene naphthalate (BN) content correlates with enhanced material strength and reduced fragility. The paper highlights experimental methods, synthesis, and evaluates key relationships between the properties of the copolymers and their aging processes.
