摘要： Substantially linear olefin polymers having a melt flow ratio, I.sub.10 /I.sub.2, .gtoreq.5.63, a molecular weight distribution, M.sub.w /M.sub.n, defined by the equation: M.sub.w /M.sub.n (I.sub.10 /I.sub.2)-4.63, and a critical shear stress at onset of gross melt fracture of greater than about 4.times.10.sup.6 dyne/cm.sup.2 and their method of manufacture are disclosed. The substantially linear olefin polymers preferably have at least about 0.01 long chain branches/1000 carbons and a molecular weight distribution from about 1.5 to about 2.5. The new polymers have improved processability over conventional olefin polymers and are useful in producing fabricated articles such as fibers, films, and molded parts.

摘要： Easy-tear, non-halogenated, high-clarity ethylene polymer films are described that do not contain migratory additives and that are useful as a domestic food wrap. These films also exhibit high inherent cling values. In one embodiment, the film is multilayered in which the outer layers comprise a very low density heterogeneously linear polyethylene or a homogeneously branched polyethylene, preferably a substantially linear ethylene polymer, and the inner layer(s) comprise a low density polyethylene. In another embodiment, the film is a monolayer, or multiple layers of the same formula, in which the film comprises a mixture of a very low density heterogeneous linear polyethylene or a homogeneously branched polyethylene, preferably a SLEP, and a LDPE.
