Abstract

Propileno de elevada resistencia a la fusión de distribución de peso molecular amplia o bimodal, el cual imparte al producto, características reológicas tales como poder conformarse en máquinas normalmente utilizadas para resinas tales como el poliestireno. También se describen los artículos moldeados producidos a partir del propileno de la invención, al igual que un proceso continuo para producir el polipropileno de elevada resistencia a la fusión el cual se obtiene en presencia de sistema catalizado por tipo Ziegler-Natta, utilizando por lo menos dos recipientes de polimerización conectados en serie, llevándose a cabo el control del peso molecular mediante la adición de cantidades discretas de un regulador del peso molecular, tal como el hidrógeno, a por lo menos uno de los distintos recipientes de polimerización, para obtener en el primer recipiente de polimerización una parte de peso molecular superior y en los siguientes recipientes de polimerización, partes del polímero de peso molecular inferior, por medio de lo cual el polímero total exhibe una distribución de peso molecular amplia o bimodal, la cual le imparte al producto propiedades reológicas interesantes.Propylene with high resistance to melting with a wide or bimodal molecular weight distribution, which imparts to the product rheological characteristics such as being able to be shaped in machines normally used for resins such as polystyrene. Molded articles produced from the propylene of the invention are also described, as well as a continuous process to produce polypropylene with high resistance to melting, which is obtained in the presence of a Ziegler-Natta type catalyzed system, using at least two polymerization vessels connected in series, molecular weight control being carried out by adding discrete amounts of a molecular weight regulator, such as hydrogen, to at least one of the different polymerization vessels, to obtain in the first polymerization vessel a higher molecular weight part and in subsequent polymerization vessels parts of the lower molecular weight polymer, whereby the total polymer exhibits a broad or bimodal molecular weight distribution, which imparts to the product interesting rheological properties.
