  • Multifunctional Coatings on Microporous Substrates
    Publication number: 20150202577
    Abstract: A composition is described wherein a coating is provided on a microporous substrate, such as a low surface energy microporous substrate, which coating provides multiple functionalities to the underlying microporous material, while still maintaining porosity within at least a portion of the microporous substrate.
    Type: Application

  • Process for making crosslinked polyvinylpyrrolidone
    Patent number: 6660800
    Abstract: A process for making crosslinked polyvinylpyrrolidone (PVP-P) is disclosed. Crosslinker generation, followed by polymerization of NVP, gives a polymer containing up to 4 wt. % of residual NVP. An aqueous mixture of the polymer is then heated in the presence of a protic acid at pH<4 to eliminate NVP. Finally, the PVP-P is neutralized with aqueous alkali metal hydroxide. The process generates a reduced volume of low-toxicity aqueous waste (<20 L/kg PVP-P) and gives PVP-P that meets important product specifications.

  • Olefin epoxidation using a carbon molecular sieve impregnated with a transition metal
    Patent number: 5319114
    Abstract: Olefins are selectively converted to epoxides by reacting with an organic hydroperoxide in the presence of a heterogeneous catalyst comprised of a carbon molecular sieve containing a Group IVA, VA, VIA, or VIIA transition metal such as molybdenum.

  • Hydroformylation process and bimetallic catalyst therefor
    Patent number: 5276210
    Abstract: An improved allyl alcohol hydroformylation process and catalyst are disclosed. The process uses a catalyst system comprising a Group VIII metal carbonyl complex catalyst, a trisubstituted phosphine, a neutral Group VIII(a) metal complex cocatalyst, and optionally, a diphosphinoalkane. The process uniquely gives an enhanced linear:branched aldehyde product ratio.
