Abstract: The invention provides a composition which can be used as a polymer processing aid in polyolefin extrusion processes, the composition comprising:
(a) a polyolefin; and
(b) 0.01 to 50 wt.-% of a functionalized poly(dialkyl siloxane) copolymer having the formula

wherein R is an alkyl group containing 1 to 8 carbon atoms, R 1 and R 2 are the same or different and are either alkyl or poly(oxyalkylene) chains, terminated with a polar or charged functional group selected from an alcohol, a primary or secondary amine, or a combination of primary and secondary amines, an ammonium ion, or a phosphate;
where m is from 1 to 15,000, n is from 0 to 15,000, and p is from 0 to 5000;
where X is R or R 1 ;
where Z is R or R 1 ;
with the proviso that when either one or both of X and Z are R 1 , then n and p are both 0, and when both X and Y are R, then n is at least 1...

Abstract: Provided are multilayer films including ethylene-based polymers. The multilayer films can be fully compatible with polyethylene recycling streams. The multilayer films include a first outer layer, a second outer layer, and a core, the core including a first core layer that includes an ethylene-propylene copolymer. The multilayer films of the present invention can exhibit improved, maintained, or desirable properties, such as high tear resistance, in comparison to existing multilayer film structures that are not fully compatible with polyethylene recycling streams.

Abstract: Provided is a polyethylene laminate, which has high recyclability, is excellent in physical characteristics, such as rigidity, strength, and impact resistance, and is excellent in heat-sealing property. The heat-sealing polyethylene laminate of the present invention includes: a stretched film of an ultra-high molecular weight polyethylene-based resin (A) having a viscosity-average molecular weight of from 300,000 to 15,000,000; and a low molecular weight ethylene-based resin layer, which is arranged on at least one side of the stretched film of the ultra-high molecular weight polyethylene-based resin (A) and includes an ethylene-based resin.
