Abstract

a invenção se refere a um pneumático com armadura de carcaça radial (2), constituída por pelo menos uma camada, que compreende uma armadura de topo (3) coberta radialmente por uma banda de rodagem (4), o dito pneumático compreendendo uma camada p de misturas poliméricas em contato com pelo menos uma camada de topo de trabalho (31, 32) e em contato com a armadura de carcaça. de acordo com a invenção, pelo menos as misturas elastoméricas que formam a camada de calandragem apresentam uma densidade relativa de pontes de enxofre inferior a 5 % e as misturas elastoméricas que formam a camada p apresentam uma densidade relativa de pontes de enxofre inferior a 5 %, as ditas misturas elastoméricas sendo composições à base de pelo menos um elastômero diênico escolhido no grupo dos elastômeros diênicos constituído pelos polibutadienos (em abreviado ?br?), pelos poliisoprenos (ir) de síntese, pela borracha natural (nr), pelos copolímeros de isopreno, pelos copolímeros de butadieno com exceção dos copolímeros butadieno-nitrila (nbr), com exclusão dos elastômeros diênicos que portam funções carboxilas, e pelas misturas desses elastômeros diênicos.
