Abstract

L'invention concerne des compositions de latex de caoutchouc sensibles à la chaleur, comprenant un latex de caoutchouc naturel et un thermo-sensibilisateur. Ces compositions sont caractérisées en ce qu'elles comprennent en outre un sel de calcium, de préférence le chlorure ou le nitrate de calcium, qui conserve à la composition sa thermo-sensibilité à des pH supérieurs à 8,5, par exemple de 10 et plus. Utilisation pour la fabrication d'articles caoutchouteux divers, par immersion d'une forme chaude dans le latex ou extrusion à travers une matrice chauffée.
