摘要： Processes for enhancing blown film processability and the blown films formed thereby are described herein. One embodiment of the processes generally includes providing a first propylene based heterophasic copolymer having a first melt flow rate, modifying the first propylene based heterophasic copolymer to form a second heterophasic polymer having a second melt flow rate, wherein the second melt flow rate is greater than the first melt flow rate, contacting the first heterophasic polymer, the second heterophasic copolymer or a combination thereof with a plurality of additives, wherein the plurality of additives include a nucleator, polyethylene and mineral oil to form a modified heterophasic copolymer and blowing the modified heterophasic polymer into a film.

摘要： It has been discovered that the properties of sheet or film materials of broad molecular weight distribution ethylene/propylene rubber impact-modified heterophasic copolymer (ICP) can be improved by blending the ICP with a second polyolefin. The second polyolefin may be a syndiotactic polypropylene (sPP), a random copolymer (RCP) of propylene and comonomer (e.g. ethylene and/or butene) made using a Ziegler-Natta or metallocene catalyst, medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), or low crystalline copolymer of propylene/α-olefin. Improvements include, but are not necessarily limited to, reduced motor amps, lower secant modulus, increased dart drop strength, increased gloss, reduced haze, increased elongation to yield, elimination of stress whitening, improved puncture resistance, and decreased seal initiation temperature. This sheet of film materials may be co-extruded with other resins or laminated with other materials after extrusion.
