  • Patent number: 8026037
    Abstract: New polymers are provided that have non-carbon tetravalent species (Si, Ti, Ge, Zr, Sn) and photoimageable compositions that contain such polymers. Preferred polymers are organic, e.g. one or more polymer repeat units comprise carbon atom(s). Particularly preferred are polymers that comprise SiO2 or TiO2 repeat units and which can be highly useful as a resin component of resists imaged at short wavelengths such as sub-300 nm and sub-200 nm.

  • Patent number: 7843560
    Abstract: The present invention relates to a turbidity calibration standard comprising: a number of from 1 to 5 sequentially-interfaced layers, wherein each layer independently comprises a light-permeable polymer or light-permeable interpolymer; a measured light transmission modulating amount of at least one light transmission modulator, which is distributed in any one or more of the layers; and a light-permeable container, which contains the layers and the at least one light transmission modulator. Also, the invention relates to methods of making and using the standard, and kits comprising the standard.

  • Patent number: 7416698
    Abstract: A process for characterizing a sample comprising a population of linear macromolecules of interest (104) and a population of long chain branched macromolecules of interest (103), the process including four steps. The first step is to provide a flow through separating medium (100) and a liquid eluant (101) in which the macromolecules of interest dissolve, the separating medium defining flow through channels (102), the eluant flow rate and the average diameter of the channels being in a range so that the linear macromolecules of interest elute before the long chain branched macromolecules of interest (105) (106). The second step is to introduce a sample into the liquid eluant. The third step is to flow the liquid eluant under pressure through the channels (102) of the separating medium (100).

  • Patent number: 5665800
    Abstract: Substantially linear olefin polymers having a melt flow ratio I.sub.10 /I.sub.2,.gtoreq.5.63, a molecular weight distribution, M.sub.w /M.sub.n, defined by the equation: M.sub.w /M.sub.n .ltoreq.(I.sub.10 /I.sub.2)-4.63, and a critical shear stress at onset of gross melt fracture of greater than about 4.times.10.sup.6 dyne/cm.sup.2 and their method of manufacture are disclosed. The substantially linear olefin polymers preferably have at least about 0.01 long chain branches/1000 carbons and a molecular weight distribution from about 1.5 to about 2.5. The new polymers have improved processability over conventional olefin polymers and are useful in producing fabricated articles such as fibers, films, and molded parts.
