  • Publication number: 20230287157
    Abstract: The present disclosure provides a process. In an embodiment, the process includes providing a multifunctional branching agent (MFBA). The MFBA has A) three or more carbon-carbon double bonds with the provisos (1) that the MFBA is not a polymer of butadiene, and (2) the MFBA does not contain an acrylate group or a methacrylate group. The MFBA has B) a total reactivity, R, greater than 3 and less than 40, (3<R<40) wherein R is determined with the following formula (I): wherein j=index of summation, p=the number of different types of carbon-carbon double bonds j in the molecule, nj=the number of each carbon-carbon double bond of type j in the molecule, and r1,j=the relative reactivity ratio (RRR) of ethylene to the carbon-carbon double bond j. The process includes reacting the MFBA with ethylene under polymerization conditions and forming an ethylene-based polymer composition composed of units of ethylene and units of the MFBA.

  • Publication number: 20230136233
    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.
