ExxonMobil adds that mPE 35-05 displays "robust and straightforward processing on both linear low density polyethylene (LLDPE) and low density polyethylene (LDPE) film-line equipment, while exhibiting processing and shrink properties approaching [those of] LDPE, with the mechanical properties of higher alpha-olefin resins of similar density.
Candidate resins include low-viscosity polyethylene and alpha-olefin homopolymers or their copolymers with propylene or 1-octene.

Titled Polyolefin Comonomers-World Markets, 1995-2005, the report quantifies and forecasts the use of butene-1, hexene-1, octene-1, and other alpha-olefin comonomers in the production of polyethylene copolymers and polypropylene multipolymers.
Incorporation of an alpha-olefin comonomer in the ethylene chains disrupts the chain regularity and therefore reduces the lamellar thickness and polymer crystallinity.
