Films containing LLDPE having a high modulus and good tear strength for the high modulus and improved processing conditions are obtained by blending minor amounts of polystyrene or other aromatic polymer, and polypropylene with the LLDPE.

Blends of LLDPE, polypropylene and aromatic polymers and high modulus

The extrudability of linear polymers of ethylene such as low density copolymers of ethylene and C.sub.4 --C.sub.10 olefins (LLDPE) into thin films is improved by adding small amounts, e.g., 0.02 to 2 weight percent ethylene-vinyl polymer to reduce melt fracture, head pressure and to obtain films having excellent anti-blocking characteristics. Optionally, diatomaceous earth is added to further reduce blocking.

Compositions of linear polyethylene and ethylene-vinyl alcohol polymer

Composition and films of linear ethylene polymers such as linear low density polyethylene containing up to about 3 weight percent of a blend of polyphenylene oxide and styrene resin exhibit excellent physical properties particularly impact strength.

High impact blends and films of linear polyethylene, polyphenylene oxide

The extrudability of linear polymers of ethylene such as low density copolymers of ethylene and C.sub.4 -C.sub.10 olefins (LLDPE) into thin films is improved by adding small amounts, e.g., 0.02 to 1 weight percent polyacetal fluoride to reduce melt fracture, head pressure and extruder torque.
