  • Publication number: 20170002108
    Abstract: The present disclosure relates to a process for preparing a MgCl2-alcohol adduct which comprises (a) forming a mixture of an MgCl2-alcohol adduct in molten form and a liquid which is immiscible with the adduct, (b) subjecting the mixture to a shear stress to obtain an emulsion, and (c) rapidly cooling the emulsion to solidify the disperse phase and collecting the solid adduct particles, the process being characterized by the fact that step (b) is carried out in a device comprising a first outer and second inner cylindrical members that define an annulus between them, wherein at least one of the cylindrical members rotate with respect to the other.

  • Patent number: 8153757
    Abstract: A solution process for polymerizing one or more ?-olefins of formula CH2?CHR, where R is H or an alkyl radical C1-12, to produce a polyolefin soluble in the reaction medium, the process comprising: a) polymerizing said one or more ?-olefins in a solution phase in the presence of a polymerization catalyst and a inert solvent having a vapor pressure lower than 100 kPa at 20° C.; b) separating the produced polyolefin from the unreacted monomers and the inert solvent by means of a sequence of at least three volatilization chambers operating at a decreasing pressure, the second devolatilization chamber being operated at a pressure from 0.8 to 5 bar.

  • Patent number: 7985812
    Abstract: A method for controlling a solution process for the polymerisation of olefins is disclosed. The method is based on an algorithm that calculates predicted operating parameters of the process, including calculation of the extent of reaction (?), as a function of the solution density (?), and then calculation of the whole composition of the solution. The algorithm resolves a system of equations comprising the equation of state in the PC-SAFT form, the Lewis-Mayo equation for monomer incorporation into a copolymer, and the stoichiometry equation. Predicted parameters are compared to target parameters to detect possible deviations and implement corresponding compensation in the feed.

  • Patent number: 7199163
    Abstract: Method for continuously removing the unreacted butene-1, and optionally other volatile components, from a polymeric solution obtained by liquid phase (co)polymerization of butene-1, the method comprising the steps of: subjecting the polymeric solution to heating and mixing conditions such that a mixture is formed consisting substantially of: (1) a polybutene melt containing entrapped butene-1 and (2) supercritical gaseous butene-1; subjecting the above mixture to a sequence of devolatilization steps operating at decreasing pressures.

  • Patent number: 7160964
    Abstract: A liquid-phase process for polymerizing ?-olefins of the formula CH2?CHR, where R is H or an alkyl radical C1–C6, to produce a polymer that is soluble in the reaction medium, comprising the steps of: a) continuously polymerizing in liquid phase the ?-olefin in the presence of a catalyst system based on a transition metal compound; b) continuously withdrawing from step a) a solution of polymer in the liquid reaction medium; c) mixing in one or more mixing stages said solution of polymer in the reaction medium with an organic deactivator having: at least a hydroxy group, a boiling point higher than 150° C., and a ratio between the molecular weight (MW) and the number of hydroxy groups (OH) comprised between 20 and 100.
