Abstract: The present disclosure provides a composition. In an embodiment, the composition includes an olefin-based polymer and from 0.15 wt % to 15 wt % of an odor suppressant. The odor suppressant includes (i) from 0.05 wt % to 2 wt % of a metal oxide having a band gap greater than 5.0 electron volts (eV), and (ii) from 0.1 wt % to 13 wt % of an acid copolymer. The ratio of metal oxide to acid copolymer is from 1:20 to 1:1. Weight percents are based on the total weight of the composition.

Abstract: The present disclosure relates to a process for preparing an olefin-acrylate block copolymer, the process comprising: a) performing atom transfer radical polymerization (ATRP) by combining ATRP materials comprising an acrylate monomer, an initiator having a radically transferrable atom or group, a transition metal compound, and a ligand, thereby forming a macroinitiator; and b) combining reaction materials comprising an alpha-substituted acrylate and the macroinitiator, thereby forming the olefin-acrylate block copolymer.

Abstract: Embodiments are directed to a method of making an olefin-based polymer by free-radical polymerization in a reactor system. The method includes initiating a free-radical polymerization of an olefin-based monomer, propagating growth of the olefin-based polymer during continued free-radical polymerization of the olefin-based monomer, and adding to the reactor system a chain transfer agent that terminates the growth of the olefin-based polymer. The chain transfer agent includes a silane. Examples of suitable silanes are: triethylsilane, diethylmethylsilane, tris(trimethylsilyl)silane, n-butylsilane, dimethylphenylsilane, phenylsilane, chlorodimethylsilane, diisopropylaminosilane, 1,2-bis(dimethylsilyl) benzene, 1,3-bis(dimethylsilyl) benzene, 1,4-bis(dimethylsilyl)benzene, 1,1, 3,3-tetramethyldisiloxane, trimethylsilane, (trimethylsilyl)dimethylsilane, and bis(trimethylsilyl)methylsilane.

Abstract: Catalyst compositions and polymerization systems include at least one thioguanidine complex according to Formula (I): MQaX4_a (I) in which M is Ti, Zr, or Hf; a is 1 or 2; each group Q of the thioguanidine complex is a bidentate thioguanidine ligand bound to the metal center and having Formula (1a) or Formula (1b), In Formulas (1a) and (1b), each group R1, R2, and R3 is independently chosen from alkyl groups or aryl groups; each group Z1 is independently chosen from alkylene groups. If a=2, groups R3 of the two groups Q are optionally linked to each other through at least one covalent bond. Each X is covalently bonded or coordinated to the metal center and is independently chosen from alkyl groups or halides. The polymerization systems may be configured to copolymerize ethylene and α-olefins.
