Description

The relationships between various chemical structures of crosslinking point and physical properties (tension set, compression set and dynamic properties) were studied on ethylene propylene rubber.<BR>The compared chemical structures of crosslinking point were C-C linkage, C-Sx-C linkge, C-R-C linkage etc.<BR>From the results, it was found that : <BR>1. Tension set and compression set were influenced not only by crosslinking density but also the chemical structure of crosslinking point under the condition of determination which changed the chemical structure of crosslinking point.<BR>2. Dynamic viscoelasticity and impact resilience seemed to be influenced by crosslinking density and the chemical structure of crosslinking point, but the effects of chemical structure of crosslinking point were recognized only in impact resilience test.
