摘要

"Modified polypropylene, and processes to increase the resistance of the molten material and / or the viscosity of the molten material extensional a (CO) polu00ecmero polypropylene.To produce a modified polypropylene, and for modification of a polu00ecmero aolefu00ecnico ".A process for modifying a (CO) polymer of polypropylene in which the said process comprises mixing of molten material of (CO) polymer of polypropylene in the presence of an initiator in the whaAl the initiator is selected from the group defined by formula (1), in which R is selected from the group consisting of C ~ 1 ~ C ~ 18 ~ - acyl, optionally substituted.C ~ 1 ~ C ~ 18 ~ - alkyl optionally substituted, arou00edla defined by formula (2) and compound of formula (3) in which u, V, x, y, Z, u ', V', X ',Y 'and Z' are independently selected from the group consisting of hydrogen, halogen, C ~ 1 ~ C ~ 18 ~ - alkyl; C ~ 1 ~ C ~ 18 ~ - ariloxi, alkoxy, acyl, aciloxi, arila, carboxy, alcu00f3xi - carbonyl.Aril - oxicarbonila, trialquila, silila, hydroxy or a group of the formula (4), and in which t is alkylene.
