A SEALANT COMPOSITION, METHOD OF PRODUCING THE SAME

摘要

The instant invention is a sealant composition, method of producing the same, articles made therefrom, and method for forming such articles. The sealant composition according to the present invention comprises: (a) from 70 to 99.5 percent by weight of an ethylene/alpha-olefin interpolymer composition, based on the total weight of the sealant composition, wherein said ethylene/alpha-olefin interpolymer composition comprises an ethylene/alpha-olefin interpolymer, wherein ethylene/alpha-olefin interpolymer has a Comonomer Distribution Constant (CDC) in the range of from 15 to 250, and a density in the range of from 0.875 to 0.963 g/cm3, a melt index (I2) in a range of from 0.2 to 20 g/10 minutes, and long chain branching frequency in the range of from 0.02 to 3 long chain branches (LCB) per 1000C; (b) from 0.5 to 30 percent by weight of a propylene/alpha-olefin interpolymer composition, wherein said propylene/alpha-olefin interpolymer composition comprises a propylene/alpha-olefin copolymer or a propylene/ethylene/butene terpolymer, wherein said propylene/alpha-olefin copolymer has a crystallinity in the range of from 1 percent by weight to 30 percent by weight, a heat of fusion in the range of from 2 Joules/gram to 50 Joules/gram, and a DSC melting point in the range of 25° C. to 110° C.
