  • Patent number: 6972311
    Abstract: It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of at least one multifunctional initiator, at least one chain transfer agent, and at least one cross-linking agent. The presence of the multifunctional initiator tends to cause more branched structures in the polystyrene. A mathematical model that helps optimize the levels of these additives for given molecular weights, melt flow indices (MFIs) and zero shear viscosities (?0) has also been discovered.

  • Patent number: 6887912
    Abstract: An expanded cellular ethylenic polymer product is provided from an irradiated, noncross-linked linear ethylenic polymer. Linear ethylenic polymers can be irradiated at ambient conditions sufficient to introduce branching in the polymer in the absence of detectable cross-linking as indicated by the absence of gels. The irradiated linear ethylenic polymer is compatible with highly branched low density polyethylene and, when mixed therewith, produces a resin having a single broad based melting temperature range as determined by direct scanning calorimetry, which indicates that the polymers in the mixture have similar crystallization behavior suitable for producing low density foams by extrusion foaming. The linear polymers can be obtained from recycled shrink wrap film. Low densities of from 0.7 to less than 4 pcf can be achieved. The foams typically have improved tear resistance as compared to previous products prepared from low density polyethylene, at comparable low densities.

  • 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: 6822019
    Abstract: The present invention discloses a complex of clay and polyoxyalkylene amine grafted polypropylene and a method for producing the same. The clay in the present invention is formed by modifying inorganic layered silicate clay with an amphibious intercalating agent obtained by polymerizing polyoxyalkylene amine having molecular weight over 1,800 and polypropylene-grafting-maleic anhydride (PP-g-MA). The method for producing the complex is primarily to polymerize the polyoxyalkylene diamine having molecular weight over 1,800 and polypropylene-grafting-maleic anhydride (PP-g-MA) to form an amphibious intercalating agent, which is then acidified with an inorganic acid, and mixed with the swelled clay by powerfully stirring at 60-80° C. for cation exchanging to obtain the titled complex. According to the present invention, the complex is an excellent surfactant and a reinforcing agent of polymers.

  • Patent number: 6673848
    Abstract: The present invention provides a process for manufacturing a cross-linked expanded safety support having a cellular structure comprising closed cells. The process involves kneading by thermomechanical working a rubber composition comprising a diene elastomer having a molar ratio of diene units (defined as units resulting from dienes) of less than 15%, water in an amount of from 3 to 6 phr (phr=parts by weight per 100 parts elastomer), a blowing agent, such as azobisformamide, that provides for formation of the cellular structure and a vulcanization system. The rubber composition so prepared is then formed, e.g. by injection or extrusion, into cross-linkable blank, which is then cured in a mold and then demolded. The demolded blank is then expanded by decomposition of the blowing agent and vulcanized to produce the cross-linked expanded elastomeric support.
