Latice Deformation and Meso-Phase Structure in Poly(Ethylene Terephthalate)From Solid State Coextrusion

摘要

The development of crystalline and Meso-phase structure by solid state extrusion from50℃ to 90℃ is studied for PET. The unit cell parameters of stress-induced crystallites inextrudates are determined as a function of extrusion draw ratio (EDR), and
