melting noncontinuous phase comprises a polypropylene polymer with melt flow rate of greater than 20 g 10 min application_number US 77384501 A description linear low density polyethylene lldpe is produced in either a solution or a fluid bed process the polymerization is catalytic ziegler natti and single site metallocene catalyst systems have been used to produce lldpe the resulting polymers are characterized by an essentially linear backbone density is controlled by the level of comonomer incorporation into the otherwise linear polymer backbone various alpha olefins are typically copolymerized with ethylene in producing lldpe the alpha olefins which preferably have four to eight carbon atoms are present in the polymer in an amount up to about 10 percent by weight the most typical comonomers are butene hexene 4 methyl 1 pentene and octene the comonomer influences the density of the polymer density ranges for lldpe are relatively broad typically from 0 87 0 95 g cc astm d 792 linear low density polyethylene melt index is also controlled by the introduction of a chain terminator such as hydrogen or a hydrogen donator the melt index for a linear low density polyethylene can range broadly from about 0 1 to about 150 g 10 min for purposes of the present invention the lldpe should have a melt index of greater than 10 and preferably 15 or greater for.
