Abstract: A polypropylene composition characterized by improved additive retention can include at least 70 wt. % of a component (A) that is a random copolymer of propylene and ethylene produced with a metallocene-based polymerization catalyst. The component (A) can have a molecular weight distribution of at most 4.0. The polypropylene composition can include from 0.001 to 2.0 wt. % of a component (B) that is an additive that migrates to a surface of the polypropylene composition. The polypropylene composition can include a component (C) that is a thermoplastic polymer different from component (A), and is not a metallocene polypropylene homopolymer. The polypropylene composition can have a gloss at 20° of at least 75. Articles can be produced from the polypropylene composition, including articles that require specific surface properties over an extended period of time.

Abstract: Heterophasic propylene copolymers can include a matrix phase and a dispersed phase. The heterophasic propylene copolymers can be characterized by good processability and good mechanical properties, particularly an improved rigidity. The heterophasic propylene copolymers can be well-suited for injection molding applications, particularly for injection molding of thin-walled articles.

Abstract: The invention relates to high purity polypropylenes and polypropylene compositions suitable for injection molding in which the polypropylene is characterized by a percentage of 2,1-insertions, relative to the total number of propylene molecules in the polymer chain, of at least 0.2%; a melting temperature Tm ranging from 140° C. to 160° C. as determined according to ISO 3146; a ratio of frequencies at fixed modulus of 1000 Pa for storage shear modulus (G′) and loss shear modulus (G″) greater than 4.7; a molecular weight distribution (MWD) of at least 2.5; a number average molecular weight (Mn) of at most 45 kg/mol and Carreau-Yasuda parameters η0, b and τ complying with the relationship: 2.18−1.715(b)−0.015(Ln η0)2+0.944(b)2+0.0149(Ln η0)(Ln τ)+0.0095(Ln τ)2>1 when fitted to the CY equation, said CY parameters η0, b and τ are determined from a dynamic rheology analysis (RDA).
