Effect of crystalline phase on the elasticity of rubbers
- 20 Downloads
The dynamic mechanical properties of crystallizing divinyl and isoprene rubbers have been investigated over a wide temperature range. It is shown that the formation of a crystalline phase in the rubber leads to a regular increase in rebound resilience in the transition temperature range. The demonstrated relation between these quantities shows that the minimum elasticity can be used as a measure of the crystalline phase present in the polymer.
