High density polyethylene modified by reaction with hydrogen peroxide to produce films and fibers.

摘要

b high density polyethylene modified by reaction with peroxido for the manufacture of films and fibers d is described a product has MFI ~ 190 / 21.6 ~ between 1.0 and 10.0 g / LOMIN; density between 0.94 and 0.97; branched molecular structure in the range between 0.5 and 3.0 LCB / ioooc polidispersu00e3o between; 4.5 and 6.5; fraction of high molar mass (MZ + 1) between 6x10 ^ 6 ^ and 8.5x10 ^ 6 ^; distribution curve massamolar with MW 10 ^ 6 ^ between 3.0% and 6.0% by mass and 10 ^ 5 ^ MW 10 ^ 6 ^ between 40% and 55% by mass. Such molecular characteristics and differentiated properties give the product extrusion processability by the blast and by extrusion followed by spinning for the production of films and fibers.
