DSC Investigation of High-Strength and High-Modulus Polyethylene Fibers

Fibers were produced from two commercial grade linear polyethylenes(PE) of different molecular weight by flow-induced crystallization. DSC measurements were carried out with an annealing and melting program. Four melting peaks were found. The first peak, at the lowest temperature, can be identified...

Description
Summary:Fibers were produced from two commercial grade linear polyethylenes(PE) of different molecular weight by flow-induced crystallization. DSC measurements were carried out with an annealing and melting program. Four melting peaks were found. The first peak, at the lowest temperature, can be identified with the melting of lamellar crystallized PE. Peak 2 corresponds to the melting of the main crystalline fraction of the fiber, and peaks 3 and 4 to the melting of constrained crystalline regions. The melting temperature depends on the molecular weight of the fiber material and on the drawing state. 7 ref.--AA
