摘要：

Effects of high energy radiation on stress relaxation behavior of unoriented (lambda = 1) and oriented (lambda = 9) ultrahigh molecular weight polyethylene (UHMWPE) were investigated. As in a previous study, the stress relaxation is interpreted in terms of a model that consists of two thermally activated processes acting parallel. The first process is related to crystal and the second to the amorphous fraction. Application of the two-process model enabled separate studying of the influence of irradiation on viscoelastic behavior of these two fractions. (C) 1999 Elsevier Science Ltd. All rights reserved.
