Effects of crosslinking and crystallinity on the properties of the thermal and rheological properties of the EVA were studied. From the Studies of storage modulus of the EVA with VA content in the solid temperature range (about -70 to 50 degrees C), the storage modulus decreased with increasing the VA content. This result suggested that the crystallinity of the EVA affected the storage modulus of the EVA because of the weak crosslinking of the EVA by DCP. From the Studies of complex viscosity of the EVA with and without DCP in the melt state, the values of the power law parameter of the EVA without DCP ranged from 0.39 to 0.50 and the EVA with DCP ranged from 0.03 to 0.12. In the measurement of the complex viscosity of the EVA in the melt state, the crosslinking affected the complex viscosity of the EVA with DCP. (c) 2005 Elsevier Ltd. All rights reserved.
