Abstract

1361241 Tyres MONTECATINI EDISON SpA 22 June 1971 [23 June 1970] 29158/71 Heading B7C [Also in Division C3] Tyres comprise a carcass and a tread adhered together, the carcass and tread each comprising a vulcanized mix comprising an elastomeric copolymer of ethylene, an α-olefin and one or more dienes and characterized by (1) an ethylene content of 60 to 80 weight per cent, (2) an elasticity modulus at 40% elongation E 40 lower than 5 kg./sq. cm., (3) an A 50 /E 40 ratio greater than 180 sq. cm./kg. where A 50 is the percentage elongation under a load of 50 kg./sq. cm., (4) a heat of fusion #H measured at 300% stretch not greater than 8 cal./g. and (5) a crystallite melting temperature at 300% stretch of less than 50‹ C. The α-olefin may be propylene or butene-1 and the diene hexadiene-1,4, dicyclopentadiene, cyclooctadiene, 6-methyl-4,7,8,9- tetrahydroindene, or 2-methallyl-, 2-isopropylidene-, 2-ethylidene- or 2-methylene-norbornene- 5.
