Abstract

COMPOSIÇÃO ELASTOMÉRICA PARA COMPOSTOS DE PNEU, COMPOSTO ELASTOMÉRICO PARA PNEUS, PROCESSO PARA A PREPARAÇÃO DE UM COMPOSTO ELASTOMÉRICO, COMPONENTE DE PNEU PARA RODAS DE VEÍCULO, E, PNEU PARA RODAS DE VEÍCULO. A presente invenção refere-se a composições para compostos elastoméricos para pneus que compreendem agentes compatibilizantes de monotetrazol distinguidos por temperaturas de ativação precisas, componentes de pneu e pneus para rodas de veículo que compreendem os mesmos. Vantajosamente, os presentes agentes compatibilizantes de monotetrazol permitem que as propriedades de quebra dos compostos sejam melhoradas enquanto mantêm uma alta compatibilização do enchimento.
