PLASTICIZED POLYOLEFIN COMPOSITIONS

摘要

The present invention relates to a polyolefm composition that includes 60 to 99 wt% of one or more polyolefm polymers and 1 to 40 wt% of a regularly branched PAO ("rbPAO") based on the total weight of the polyolefin polymer(s) and the rbPAO, wherein the rbPAO includes oligomers of one or more C2 to C20 alpha-olefms having a kinematic viscosity at 100°C ("KVlOO0C") of 3 to 3000 cSt, a Branching Irregularity Index ("BII") of 0.40 or less, a molar-average carbon number ("CLAO") of 6 to 14. Preferably, the rbPAO has a Mw/Mn of less than 2.3, a reduced TGA Volatility compared to comparable polyolefin compositions with conventional PAOs, or a reduced glass transition temperature (Tg) of the composition compared to comparable polyolefm compositions with conventional PAOs.
