  • Patent number: 8399578
    Abstract: In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.

  • Patent number: 4118555
    Abstract: Petroleum resins are prepared by subjecting to pre-polymerization a hydrocarbon fraction containing olefins and diolefins, having a boiling range of from 30.degree. to 300.degree. C, in the presence of activated clays, recovering from the pre-polymerization products a selected hydrocarbon fraction having a boiling point not exceeding 250.degree. C, mixing this selected fraction with a hydrocarbon fraction containing unsaturated hydrocarbons with an average of 5 carbon atoms per molecule, subjecting the resulting mixture to polymerization in the presence of a Friedel-Crafts catalyst and recovering the petroleum resins from the polymerization products. These petroleum resins form homogeneous mixtures with rubber.

  • Patent number: 4105843
    Abstract: A hydrocarbon resin having improved color and thermal stability is prepared from a petroleum cracking or reforming fraction containing cationically polymerizable hydrocarbons and having a boiling range of 140.degree. to 280.degree. C. The petroleum fraction is first heat-treated with an .alpha., .beta.-unsaturated dicarboxylic acid anhydride at 50.degree. to 250.degree. C., and then polymerized in the presence of a catalyst. The hydrocarbon resin is useful as a binder component in hot-melt adhesives, pressure-sensitive adhesives and thermofusible traffic paints.

  • Patent number: 4096103
    Abstract: A pressure-sensitive adhesive composition consisting essentially of a natural or synthetic tackifier, an elastomer comprising isoprene and piperylene and a solvent. The elastomer is preferably prepared from certain selected copolymerized C.sub.5 -hydrocarbons from a hydrocarbon mixture containing C.sub.5 -monoolefinic hydrocarbons, C.sub.5 -diolefinic hydrocarbons (cyclic and acyclic), C.sub.5 -paraffins, C.sub.6 -aliphatics, and benzene.The elastomers thus formed, when mixed with certain natural or synthetic tackifiers, have the required tack of pressure-sensitive adhesives.
