INTERPOLIMEROS OF AROMATIC MONOMEROS OF ALFA-OLEFINA / VINILIDENO AND 7O MONOMEROS OF CYCLALIFATIC OR ALIFATIC VINYLIDENES WITH STERIC IMPEDIMENT.

摘要

THE PRESENT INVENTION REFERS TO AROMATIC MONOMERO COPOLIMEROS OF AL -OLEFINA / VINYL WITH CHARACTERISTIC SIGNS IN THEIR NMR SPECTRUM IN ITS CARBON 13. SPECIALLY, THE ETHYLENE / STYLENE COPOLYMERS OF THE PRESENT INVENTION SHOWS THOSE THAT PICTURES SHOW WITHIN THE DOMAIN OF CHEMICAL DISPLACEMENT INCLUDED BETWEEN 43.70 AND 44.25 PPM, PREFERIBLY BETWEEN 43.75 AND 44.25 PPM AND BETWEEN 38.0 AND 38.5 PPM, SO THAT SUCH PEAKS EQUIVALATE AT LEAST THREE TIMES NOISE FROM PICO TO PICO. THESE COPOLYMERS ARE OBTAINED THROUGH POLYMERIZATION OF A PROPER MIXTURE OF MONOMEROS, IN THE PRESENCE OF A CATALYST LIKE THE DICLORIDE OF (DIMETILSILANODIIL (2 - METHYL - 4 - PHENYLINDENYL) ZIRCONY). THE DESCRIBED POLYMERS PRESENT AN INCREASED MODULE, DETERMINED FROM THE TRACTION / DEFORMATION CONTRACTION DUE TO THE TRACTION AND DYNAMIC MECHANICAL PROPERTIES AT COMPARABLE VINYL AROMATIC MONOMERO LEVELS.
