Abstract: Melt-blown webs having a widened process window and better barrier properties (3rd drop, cm H2O resp. mbar). The melt-blown webs are made from so-called “controlled rheology” propylene (CR-PP), which has been visbroken without the use of peroxide but with a specific type of visbreaking additive.

Abstract: The present invention relates to crosslinkable polyolefin compositions, to a process for their preparation, to crosslinked compositions such as foams, sealants or adhesives and shaped articles, and their use in food packaging, textile packaging and technical and protection films. The crosslinkable polyolefin composition comprises one or more polyolefin polymers A, a hydrolysable silane functional polyolefin polymer B prepared from monomers comprising olefin monomers a) and silane functional compound(s) b), wherein the silane functional polyolefin polymer B is grafted onto the one or more polyolefin polymers A. The crosslinkable polyolefin compositions is crosslinkable by moisture.
