  • Publication number: 20160108221
    Abstract: This disclosure relates to a continuous solution polymerization process wherein production rate is increased. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst formulation are injected into a first reactor forming a first ethylene interpolymer. Process solvent, ethylene, optional comonomers, optional hydrogen and a heterogeneous catalyst formulation are injected into a second reactor forming a second ethylene interpolymer. The first and second reactors may be configured in series or parallel modes of operation. Optionally, a third ethylene interpolymer is formed in an optional third reactor, wherein an optional heterogeneous catalyst formulation may be employed. In a solution phase, the first, second and optional third ethylene interpolymers are combined, the catalyst is deactivated, the solution is passivated and following a phase separation process an ethylene interpolymer product is recovered.

  • Patent number: 9315661
    Abstract: In the solution polymerization of ethylene co and homopolymers the solution leaving the reactor is heated to separate polymer from solvent and residual monomers. Fouling in the heat exchanger may be reduced by adding to the solution from 0.01 to 100 ppm by weight of a polyoxyalkylene compound of the formula HO—(CH2CH2O)M[CH2CH(CH3)O]N(CH2CH2O)PH wherein M, N and P each represent the average number of repeating units and M is from 0 to 20, N is from 2 to 50 and P is from 0 to 20 and passing the solution through a heat exchanger to increase its temperature by at least 20° C.

  • Patent number: 9310192
    Abstract: Alignment of layers during manufacture of a multi-layer sample is controlled by applying optical measurements to a measurement site in the sample. The measurement site includes two diffractive structures located one above the other in two different layers, respectively. The optical measurements include at least two measurements with different polarization states of incident light, each measurement including illuminating the measurement site so as to illuminate one of the diffractive structures through the other. The diffraction properties of the measurement site are indicative of a lateral shift between the diffractive structures. The diffraction properties detected are analyzed for the different polarization states of the incident light to determine an existing lateral shift between the layers.
