  • Polyolefin based elastic compositions, methods of manufacturing thereof and articles comprising the same
    Patent number: 11230641
    Abstract: Disclosed herein is a film comprising a polymer blend, the polymer blend comprising a first polyolefin elastomer having a weight average molecular weight of 120,000 to 350,000 grams per mole; and a second polyolefin elastomer having a weight average molecular weight of 15,000 to 75,000 grams per mole; wherein the overall melt index of the polymer blend is less than 8 g/10 minutes when measured as per ASTM D1238 at 2.16 kilograms at 190° C. Disclosed herein too is a method of manufacturing a film comprising blending a first polyolefin elastomer having a weight average molecular weight of 120,000 to 350,000 grams per mole; and a second polyolefin elastomer having a weight average molecular weight of 15,000 to 75,000 grams per mole to form a polymer blend; wherein the overall melt index of the polymer blend is less than 8 g/10 minutes when measured as per ASTM D1238 at 2.16 kilograms at 190° C.; and forming the polymer blend into a film.
