摘要

"That u00e9utilizu00e1vel vulcanisable rubber composition for the manufacture of a carcass depneumatico, preparation process of umacomposiu00e7u00e3o rubber and tyre carcass.The present invention relates to a composition of borrachavulcanizu00e1vel primarily intended for the manufacture of carcau00e7asde tyres.And a housing which comprises a pneumatic band derodagem such composition, which apresentampropriedades hysteretic and physical improvement in estadovulcanizado,At the same time, retain properties deutilizau00e7u00e3o satisfactory in non cured state.Umacomposiu00e7u00e3o rubber according to the invention compreendeuma white cargo which reinforces.And she 's such a copolymer comprising - at least diu00eanico of blocks that are intended to interagircom that white cargo which reinforces and covers.At least one of its ends of chain, a blocopoliu00e9ter whose molecular mass is understood essencialmenteentre 1000 g / mol and 3000 g / mol,And the block poliu00e9tertem formula below (I) - (CH 2 CH ~ ~ ~ 2 ~ -) ~ n ~ r, where n is a whole number natural non null and R is a group hidrocarbonetosaturado or not.
