Provided is an ethylene-based modifier with which a film having good slipperiness and relatively less fish eyes can be formed. The ethylene-based modifier has a strain-hardening exponent of 0.27 or more and 0.53 or less as determined by the LAOS method.

Provided herein are polymer compositions and methods of making them, including blending a polymer and a polyethylene glycol (PEG) masterbatch. The PEG masterbatch can include one or more PEGs each having molecular weight less than 40,000 g/mol. The polymer can be a C.sub.2-C.sub.6 olefin homopolymer or a copolymer of two or more C.sub.2-C.sub.20 α-olefins. The PEG masterbatch and resulting polymer composition is preferably free or substantially free of fluorine, including fluoropolymer-based PPAs.

The present disclosure provides a thermoplastic resin composition having high rigidity and a low coefficient of linear thermal expansion and a molded article including the same. The thermoplastic resin composition includes a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent as appropriate, and thus a molded article produced therefrom can exhibit improved mechanical rigidity, impact resistance, and dimensional stability. Even when formed to a low thickness for weight reduction, the molded article can be imparted with excellent processability, high tensile strength, a high flexural modulus, and high impact strength.
