  • Patent number: 6482910
    Abstract: A polymer composition comprising a polynorbonene backbone and pendant cyclotriphosphazene groups has been developed. The pendant cyclotriphosphazene group can have various substituents such as C1-C10 alkyl, C1-C10 haloalkyl, C3-C6 cycloalkyl, phenyl, substituted phenyl, aryl, —(CH2CH2OCH2CH2)nOCH3 in which n is a positive integer, aminoalkyl, alkoxyalkyl, phenoxyalkyl, aryloxyalkyl and amidoalkyl. The polynorbonene backbone can have substituents such as H, CH3, X which is a halo group, and C2-C6 alkyl, C3-C6 cycloalkyl, C2-C6 alkoxy, phenoxy, and aryloxy. In a preferred embodiment, the pendant triphosphazene group can have either —CH2CF3, phenyl, 4-ethylcarboxylatophenyl, —CH2CH3, or —CH2CH2OCH2CH2OCH3 while the polynorbonene backbone can have H and low alkyl groups. The polyphosphazene compositions can be prepared readily via ring-opening-metathesis-polymerization of an olefin having norbornene structure with pendant cyclotriphosphazene groups.

  • Patent number: 6436878
    Abstract: The invention relates to a rheology stabilizer or thinner for high-temperature high-pressure high-mineralized degree drilling fluids, methods of their preparation and use. The rheology stabilizer is a copolymer synthesized by an olefinic acid, ester of an olefinic acid, a sulfonic acid containing unsaturated linkage(s), an amide or imide containing unsaturated linkage(s), a quaternary compound containing olefinic linkage(s) reacting chemically with phosphorous acid or hypophosphorous acid, more particularly, copolymer of acrylic acid, 2-hydroxypropyl acrylate, N-(4-sulfophenyl)-maleimide, allyltrimethylammonium chloride and phosphorous acid. The copolymers have very high resistance to high-temperature high-pressure high-valence ions, can high-effectively adjust the rheology and thixotropy of drilling fluids, and can be used as the rheology stabilizer, thinner, clay and shale stabilizer of drilling fluids.

  • Publication number: 20020037983
    Abstract: A suspending agent-containing slurry is disclosed which comprises a dispersant and a particulate suspending agent having a particle size distribution in which the particle diameter at weight-cumulative 95%, from the minimum particle size, is 1 &mgr;m or smaller. A method for efficiently producing the suspending agent-containing slurry is also disclosed. A process for suspension polymerization by use of the suspending agent-containing slurry is further disclosed. The slurry not only has such an excellent suspending ability in suspension polymerization that it enables the production of vinyl polymer beads having a narrow bead size distribution, but also is capable of retaining this ability over long and of exhibiting the same ability even when it has a high concentration. The suspension polymerization process enables vinyl polymer beads having a narrow bead size distribution to be produced efficiently due to the use of the slurry.

  • Patent number: 6355743
    Abstract: In a process for producing vinyl chloride polymers including polymerization of vinyl chloride or a monomer mixture containing it in an aqueous medium using a polymerization initiator, the polymerization is carried out in the presence of a chelating agent. The chelating agent is capable of chelating iron (II) and iron (III). This process makes it possible to prevent polymer scales from adhering to, e.g. baffle surfaces facing inner walls of the polymerization vessel, which has been hitherto difficult to do so, and less cause initial discoloration of polymer products to improve quality. It is more effective to use a polymerization vessel previously provided with coating films of a polymer scale preventive agent on the inner walls of the polymerization vessel and the other portions with which monomers come into contact in the course of polymerization.
