Abstract
Procedimiento de preparacion de copolímeros de-1-3-butadieno y estireno,utiles para la fabricacion de neumáticos o materiales elásticos, caracterizados por una resistencia a la rodadura reducida sin detrimento de otras propiedades como la resistencia al patinado. El soporífero se prepara mediante polimerizacion anionica de 1-3-butadieno y estireno y acoplamiento de parte de las cadenas en forma de estrella con un compuesto de estaño o silicio adecuado, terminando el resto de las cadenas lineales sin acoplar mediante otro compuesto de estaño seleccionado adecuadamente. La presencia de estas cadenas lineales terminadas con estaño produce un efecto beneficioso en la disminucion de la resistencia a la rodadura cuando el citado producto se emplea en formulaciones de neumáticos. La invencion se refiere también a los copolímeros de 1,3-butadieno y estireno obtenidos por dicho procedimiento.
