HOMOPOLIMEROS Y COPOLIMEROS PDF

The present invention relates to new polymers and, in particular, to new copolymers having a wide distribution of molecular weight, toughness and a capacity of Enhanced processing. In recent years there have been many advances in the production of polyolefin copolymers as a result of the introduction of metallocene catalysts. Catalysts of metallocenes offer the advantage of having an activity in general greater than traditional Ziegler catalysts and usually describe as catalysts that are of a single point nature. Due to its single point nature, the polyolefin copolymers produced by metallocene catalysts are usually very uniform in As for its molecular structure. For example, compared to the materials produced by the Ziegler catalysts traditional, said copolymers have weight distributions relatively narrow molecular MWD and narrow distribution of short chain branches SCBD. Although certain properties of the metallocene products are enhanced by the narrow MWD, difficulties are often encountered in the processing of these materials to transform them into useful articles and movies in relation to the materials produced by Ziegler catalysts.
