Notes:
Experimental ethylene-propylene-1,4-hexadiene polymers covering a range of compositions which possess satisfactory processing characteristics and economics have been evaluated in passenger car tires with emphasis on groove cracking. The tearing energy criterion was used in a laboratory test to correctly predict the groove cracking behavior of the tires made from these polymers. Road tests indicate that ethylene-propylene-1,4-hexadiene tripolymers containing 36%-42% propylene and 1.8%-2.2% diene exhibit resistance to cut growth and abrasion which is superior to standard SBR-BR bias tires. Polymers containing more than 42% propylene or 2.2% diene were inferior in wear and resistance to groove cracking, but sufficient data are not available to pinpoint the reason.
