The present invention relates to (1) at least one ethylene polymer having a comonomer content of at least 0.89 g / mL and less than 0.935 g / mL and an alpha olefin of from 0.5 to 50% by weight with more than two and less than 20 carbon atoms per molecule or A mixture containing a blend of ethylene polymers and (2) a coupling amount of at least one poly (sulfonyl azide) is sufficient to decompose at least 80% by weight of the poly (sulfonyl azide) and produce a coupled polymer. A method of making a coupled polymer, characterized by heating above the decomposition temperature of the poly (sulfonyl azide) for a period of time. The amount of poly (sulfonyl azide) is preferably 0.01 to 5% by weight of the polymer in the mixture. The present invention also includes any compositions that are products of any of the methods of the present invention and products made from these compositions, in particular any films of any of the compositions of the present invention. In addition, the present invention includes the use of any of the compositions 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, co-operative films or geomembrane, foodstuff sacks, sealing layers, bonding layers, product bags, garment bags, shipping colors, medical films, stretching Products of the compositions of the invention that are films, shrink films, agricultural films, greenhouse films, working films, or stretching hoods. |
