Abstract: A silicone-polyolefin composition is disclosed. The silicone-polyolefin composition comprises (A) a polysiloxane, (B) In a functionalized polyolefin, (C) a polyolefin that is not reactable with components (A) or (B), and (D) a curable silicone comprising at least one of an elastomer component or a liquid rubber. The polysiloxane (A) comprises an average of at least one functional group X per molecule, and the functionalized polyolefin (B) comprises an average of at least one functional group Y per molecule, where the functional group X and functional group Y are reactable to form a bond therebetween. A silicone-polyolefin blend, a curable composition comprising the silicone-polyolefin blend, a cured product of the curable composition, and methods of preparing the silicone-polyolefin blend, curable composition, and cured product are also disclosed.

Abstract: A method for reducing an amount of a contaminant in a thermoplastic polymer comprising shearing a combination comprising a contaminated thermoplastic polymer in melt form, water, and a dispersing agent where the shearing causes a portion of the contaminant to be removed from the contaminated thermoplastic polymer (e.g. moved into an aqueous phase with the water or into another separate phase from the water and the polymer), and after shearing, separating the thermoplastic from the aqueous phase to recover thermoplastic polymer.
