  • Monovinlyaromatic polymers compositions comprising high viscosity metallocene catalyzed poly-alpha-olefin additives
    Patent number: 11193006
    Abstract: The invention relates to a composition comprising a rubber-modified monovinylaromatic polymer comprising: 70 wt % or more of a monovinylaromatic polymer matrix, from 2 to 12 wt % of at least one rubber, and from 0.1 to 3.4 wt % of metallocene-catalyzed poly-alpha-olefins (mPAO) all based on the total weight of the rubber-modified monovinylaromatic polymer, with the mPAO having a kinematic viscosity of at least 950 mm2/s at 40° C. and at most 2,000 mm2/s at 40° C. as measured according to ISO 3104. The invention also relates to articles made from such composition and to the process to produce said composition and said articles.

  • Improved Monovinlyaromatic Polymer Composition Comprising Biopolymer
    Publication number: 20200190308
    Abstract: The invention relates to compositions comprising a rubber-modified monovinylaromatic polymer comprising 70 wt % or more of a monovinylaromatic polymer matrix, based on the total weight of the rubber-modified monovinylaromatic polymer, and from 0.5 to 20 wt % of at least one rubber, and from 0.1 to 4.8 wt % of at least one biopolymer based on the total weight of the rubber-modified monovinylaromatic polymer wherein at least one biopolymer is selected from poly(?-hydroxyacids) and/or polyhydroxyalkanoates, and any combination thereof; and from 0.1 to 6.0 wt % of a plasticizer being selected from a mineral oil and/or polyisobutene as based on the total weight of the composition. The invention also relates to articles made from these compositions.
