| titleOfInvention | Composition and films thereof |
| abstract | The present invention includes a composition comprising (a) at least one propylene polymer coupled by reaction with a coupling amount of poly(sulfonyl azide) sufficient to increase the melt strength of the propylene polymer before coupling at least 1.5 fold as compared with the resulting coupled propylene polymer; and (b) at least one ethylene polymer wherein the ethylene polymer is present in an amount sufficient to improve film mechanical properties of tear resistance in either the machine direction (MD) and cross direction (CD) as measured by the Elmendorf Tear method (ASTM D-1922) or dart impact strength as measured by the procedure of ASTM D-1709 or a modified method thereof in which the height from which the dart is dropped is decreased from 26' to 10.5' (0.66m to 0.27m) as compared with a film formed in the same manner using the coupled propylene polymer of (a) alone. Preferably, the propylene polymer is present in an amount of greater than 50 weight percent of the resulting composition and the ethylene polymer is present in an amount of from 5 to 49 weight percent. The invention also includes any blown film blown from a composition of the invention, particularly when blown on a high or low stalk extruder or coextruded as well as the process of blowing such a film. Further, the invention includes any article comprising a composition of the invention or comprising a film of the invention. Particular embodiments are those articles including an institutional liner, consumer liner, heavy duty shipping sack, produce bag, batch inclusion bag, pouch, grocery bag, merchandise bag, packaging, cereal liner, soft paper overwrap, multi-wall bag, lamination or combination thereof, including multiwall or multilayer configurations thereof. Further, the invention includes the use of a composition of the invention for making a blown film. |
