  • Patent number: 6831107
    Abstract: Personal care or cosmetic oil in water emulsions include an oil emulsifier and a combination of a Xanthan polysaccharide and a polyglucomannan polysaccharide to provide enhanced stability even at low emulsifier stabiliser levels. The emulsifier stabiliser system provides stable emulsions without dominating system rheology, particularly viscosity. Thus, the emulsions can have a low viscosity suitable for formulation as milks or thin lotions, or can be thickened, desirably by thickening agents other than the Xanthan and/or polyglucomannan, to provide emulsion creams or gels. This enables the system to be used very flexibly in end use applications. The emulsifier is desirably a non-ionic emulsifier and particularly is a combination of a low HLB and a high HLB emulsifier and can be formulated with conventional alcohol ethoxylate surfactants or from non-EO surfactants e.g. sucrose ester high HLB surfactants and citrate or sorbitan ester low HLB surfactants.

  • Patent number: 6831111
    Abstract: Polymeric products which after special cross-linking become macroreticular and acquire the ability to absorb organic solvents and petroleum products which are released in the water, in the amount of 40-80 gram of oily matter/gram of polymer. The macroreticular polymers include polystyrene, trimeric copolymer with styrene, ethylene, butadiene (SEBS) elastomeric SBR with styrene 10%, 20% and 40% fully hydrogenated to saturation, which after special cross-linking in chlorinated solvents with a cross-linking agent forms a thick cross-linked mass which is cut and deodorized. These products are used in a polypropylene net and are swept on the surface of water basins, harbors or the surface of sea to collect the oily matter and the petroleum by endomolecular absorption and by external surface adherence, and the loaded net is washed with petroleum to remove all absorbed oily matter as useful fuel. The net with the absorbing polymers is then ready for reuse.

  • Patent number: 6831115
    Abstract: Modified polyolefins are produced by reacting a functionalized polyolefin with one or more ethylenically unsaturated compounds having a functional group reactive with the functional group on the polyolefin. These modified polyolefins may then polymerize in the presence of a photoinitiator upon exposure to ultraviolet radiation and also have the capability of copolymerizing in the presence of a photoinitiator with other ethylenically unsaturated crosslinking agents upon exposure to ultraviolet radiation. These modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines, and therefore may be rendered water-dispersible. The modified polyolefins of the present invention significantly improve the adhesion of paints, inks, and adhesives to various plastic and metal substrates.

  • Patent number: 6831116
    Abstract: Novel modifying agents contain a sharply-melting crystalline polymer ingredient, preferably a side chain crystalline (SCC) ingredient, and an active chemical ingredient. Such modifying agents, especially when in the form of particles, can be placed in contact with a matrix, will not modify the matrix below the crystalline melting point Tp, but will rapidly modify the matrix above Tp. The active chemical ingredient can react with the matrix, catalyze a reaction of the matrix, or inhibit a reaction of the matrix. Particularly useful compositions are polymer precursors which are storage-stable at low temperatures but which are rapidly converted to crosslinked resins when heated to temperatures above Tp, optionally in the presence of light.

  • Patent number: 6831117
    Abstract: With the hardener particle of the present invention, because siloxane or an alkoxy group is bonded to a central metal located on a surface, an adhesive prepared by dispersing the hardener particles in an epoxy resin together with a silane coupling agent hardly causes reaction between the hardener particles and the silane coupling agent at ambient temperature whereby the preserving property of the adhesive is high. Because no siloxane is bonded to metal chelate or metal alcoholate at the part other than the surface of the hardener particles, the hardener particles are broken when the adhesive is heated, and the metal chelate and the metal alcoholate on the part other than the surface of the hardener particles reacts with the silane coupling agent to form cation, thereby polymerizing the epoxy resin with the cation to harden the adhesive even at low temperature within shorter time.

  • Patent number: 6831133
    Abstract: The preparation of allylated poly(vinyl chloride) by utilizing an allyltrialkylsilane in the presence of Friedel-Crafts acids is disclosed. The pendant allyl groups can be further reacted through various functionalization reactions to contain end groups such as epoxy and hydroxyl. Alternatively, an unsaturated group can be added to poly(vinyl chloride) utilizing a diene also in the presence of a Friedel-Crafts acid. These pendant groups can also be reacted to contain functional end groups such as hydroxyl and epoxy. In yet a further embodiment, the functionalized end groups such as pendant —OH groups of both the allylated and diene grafted poly(vinyl chloride) are further reacted with other monomers or polymer chains which thus results in a poly(vinyl chloride) chain having pendant monomers or polymers. These compositions are useful as compatibilizers for poly(vinyl chloride) and various other resins.
