| Number | Title | Issue Date |
| 5439992 | Continuous process for making melt-processable optical grade ring-opened polycyclic (co)polymers in a single-stage multi-zoned reactor A continuous process for the solution polymerization of appropriate polycycloolefins in a ROMP zone to obtain a processable ROMP homo- or copolymer in solution, and subsequent hydrogenation of the ROMP (co)polymer without removing the residual ROMP cataly... | 08/08/1995 |
| 5407699 | Electrically conductive pyrrole polymers A process is provided for forming an electrically conductive polymer of a pyrrole monomer, optionally substituted at the 3- and 4- positions. The process comprises dispersing a polymerization initiator selected from the group consisting of anhydrous halid... | 04/18/1995 |
| 5385780 | Sinterable mass of polymer powder having resistance to caking and method of preparing the mass Particles of a fine powder of a thermoplastic synthetic resin (host powder) having a suitable broad range between its initial glass transition temperature (initial Tg) and its final Tg, are partially coated with an anti-caking coatin... | 01/31/1995 |
| 5319034 | Process for making a polymer for an optical substrate by hydrogenating a cycloolefin copolymer Substantially optically clear molding compositions comprising polymerized cycloolefin monomers (e.g., norbornene-type polymers) which, subsequent to polymerization have been hydrogenated are provided. The polymers have a weight average molecular weight of... | 06/07/1994 |
| 5312984 | Amidation of vinyl chloride with dimethylamine using a supported palladium catalyst A continuous process for making N,N-dimethylacrylamide (NNDMA) is disclosed which uses a commodity chemical, namely vinyl chloride (VCl), which is amidated with dimethylamine (DMA) and carbon monoxide in the presence of a supported palladium(O) triorganop... | 05/17/1994 |
| 5304329 | Method of recovering recyclable unsintered powder from the part bed of a selective laser-sintering machine This method teaches how to recover and reuse a powder of a thermally degradable material which is used in a selective laser sintering (SLS) process. To recycle such a laser-sinterable powder successfully in a SLS machine it is protected against degradatio... | 04/19/1994 |
| 5239071 | Process for methylating a hindered nitrogen atom in an inert non-aqueous solvent A process for methylating the N4 atom of a polysubstituted piperazine or piperazin-2-one ("PSP") is effective despite using a much smaller molar excess of formaldehyde and formic acid than dictated by a conventional Eschweiler-Clarke reaction. ... | 08/24/1993 |
| 5185108 | Method for producing wax microspheres A process is disclosed for producing wax microspheres from molten wax. Hot water or other motive liquid in which molten wax is immiscible, is flowed under pressure through an orifice zone into which the molten wax is drawn to form a dispersion of molten w... | 02/09/1993 |
| 5159113 | Process for the palladium-catalyzed amidation of vinyl chloride A unique two-step process is disclosed for the surprisingly high rate of amidation of vinyl chloride (VCl) with carbon monoxide and certain amines catalyzed by an effective amount of monodentate tertiary phosphonium complexes of Pd(0). The rate is orders ... | 10/27/1992 |
| 5052381 | Adhesive wound dressing and perforated shield A simple construction of a two-component adhesive film, external wound dressing, comprises a backing sheet of thin, preferably elastomeric and water vapor-permeable film protected by a release layer comprising two release sheets. The sheets not only prote... | 10/01/1991 |
| 5013836 | Process for methylating a hindered nitrogen atom in a polysubstituted diazacycloalkan-2-one The difficulty of methylating a hindered piperidinyl, piperazinyl, or diazepinyl group with an Eschweiler-Clarke ("E-C") procedure without using a large molar excess (more than double) of formaldehyde is surprisingly found to be non-existent in the case o... | 05/07/1991 |
| 4983689 | Process for making macromolecular monomers of polylactones with terminal acryloyl unsaturation and block copolymers thereof Preparation of a macromolecular monomer of a lactone having an alpha-beta monoolefinically unsaturated "head" is effected at low temperature with a strong oxonium salt, such as a trialkyloxonium (TAO) hexafluorophosphate catalyst, with essentially no form... | 01/08/1991 |
| 4920228 | N,N-disubstituted, -(3,5-dialkyl-4-hydroxyphenyl)-,-disubstituted acetamides and composition stabilized therewith N-substituted, N-(polysubstituted-4-piperidinyl)--(3,5-dialkyl-4-hydroxyphenyl)-.a lpha.,-disubstituted acetamide ("3,5-DHPIPA") generates an exceptionally stable hindered acetamide aroxyl radical which is far more stable than the "blue ... | 04/24/1990 |
| 4914232 | Polysubstituted 2-morpholones, related compounds, processes for their preparation, and U-V light stabilized compositions An essentially single stage reaction has been discovered in which a disubstituted ethanolamine, that is, a 2,2'-substituted-2-aminoethanol, may be reacted with a haloform and a carbonyl containing compound selected from the group consisting of monoketones... | 04/03/1990 |
