(57) [Summary]nThe invention relates to (1) a density of at least 0.89 g / mL and less than 0.935 g / mL, and 0.5 to 50 weight percent of an α-olefin having more than 2 and less than 20 carbon atoms per molecule. % Of at least one ethylene polymer or a blend of ethylene polymers and (2) a combined amount of at least one poly (sulfonyl azide) with at least one poly (sulfonyl azide). A process for making a coupled polymer comprising heating to at least the decomposition temperature of the poly (sulfonyl azide) for a period of time sufficient for 80% by weight to decompose and to produce the coupled polymer including. Preferably, the amount of poly (sulfonyl azide) is from 0.01 to 5% by weight of the polymer in the mixture. The invention also includes compositions that are products of the method of the invention and articles made from these compositions, particularly films of the compositions of the invention. Furthermore, the present invention includes the use of the composition of the present invention in a method of blowing, casting or calendering a film. More specifically, the present invention relates to garbage bags, agricultural films, architectural films or geomembrane, food bags, sealant layers, tie layers, vegetable bags, clothing bags, transport bags, medical films, stretched films, shrink films. , Agricultural films, greenhouse films, architectural films or stretched hoods. |
