Crystal lamella polyethylene, annealing

The DSC trace also gives information on the range of lamellar crystal perfection, since the thinnest, lowest molecular weight, lamellae melt some 30 °C below the final melting point. If a rapidly cooled polyethylene is subsequently annealed in this temperature range, the lamellae will thicken by a process of partial melting and recrystallisation, and the shape of the DSC trace will change. [Pg.88]

The crystallization behavior of PBS is similar to that of polyethylene the thickness of the lamellae depends upon the crystallization temperature, and thickening of the lamellae occurs by annealing. [Pg.358]
