摘要: Dynamic vulcanization was studied in terms of the change α-relaxation temperatures LDPE matrix, morphology, and mechanical properties LDPE/ozonolysed NR blends which were vulcanized at various blend ratios with different curing systems, i.e., peroxide sulfur systems. The ozonolysed Mw = 8.30 × 105 g mol−1 Mn 2.62 mol−1, prepared by situ ozonolysis reaction natural rubber latex, used this study. significant temperature NR, dynamically using system, suggested that gave a higher degree crosslink density than corresponded improved damping property homogenous phase morphology. However, cured LDPE/ozonolyzed more improvement tensile strength elongation break system. Furthermore, strength, break, increasing ozonolyzed content both DCP blends. © 2010 Wiley Periodicals, Inc.
