    Abstract: A bituminous composition comprises a drying oily polymer of a 1,3-dione having a molecular weight of 500-20,000. The oily polymer may also be mixed up to 50% by weight of non-polymerizable polymers with or without polymerizable monomers, or of polyenes serving as cross-linking agents; and with drying natural fatty oils or with drying oils having conjugated double bonds. Other additives include free-radical forming compounds, e.g. peroxides and azo compounds, heavy metal compounds, and conventional driers, i.e. metal salts, e.g. naphthenates, caprylates and oleates of Co, Fe, Pb and Mn. The drying oily polymers may be used undiluted, or in solution or emulsified, e.g. with water, using conventional emulsifiers, and/or protective colloids. The bitumen and oily polymer may be mixed by stirring molten bitumen while pouring in or spraying the polymer, or by use of extruders, rollers and kneaders; or bituminous emulsions may be mixed with oily polymer emulsion. The composition may comprise 0.04 to 100 parts by weight of bitumen for each part of oily polymer. The oily polymer may be in chemically modified form.ALSO:A bituminous composition is made by mixing a bituminous emulsion with an aqueous emulson of an oily polymer. The composition may comprise 0.04 to 100 parts by weight bitumen, tar or asphalt per part of polymer. The polymer is a curable oily polymer of a 1, 3-diene having M.W. 500-20,000; it may have been chemically modified. Mixed with the polymer may be other polymers or monomers; polyenes; drying natural fatty oils; drying oils with conjugated double bonds; free-radical forming compounds, e.g. peroxides and azo compounds; heavy metal compounds; and conventional driers, i.e. metal salts, e.g. naphthenates, caprylates, and oleates of Co, Fe, Pb and Mn. Specified emulsifiers for the polymer are sulphonates and ethylene oxide adducts; specified protective colloids are casein, alginates and cellulose derivatives, polyvinyl alcohol, polyvinyl lactams and copolymers of vinyl lactams and amides of unsaturated carboxylic acids.

    Abstract: A 1,3-diene is polymerized in the presence of a catalyst comprising (A) a compound containing nickel in zerovalent form, and (B) a fluorine compound of boron, and in the absence of any organometallic compound of a metal of Groups IA, IIA and IIIA. The nickel compound may contain one to four ligands consisting of carbon monoxide, triarylphosphines, triaryl arsines, triaryl stilbines, esters of phosphoric acid with alkanols having 1 to 10 carbon atoms, cycloalkanols and phenols having up to ten carbon atoms, alkyl isonitriles, aryl isonitriles, pyridine, dipyridyl, o-phenanthroline nitriles of mono- and di-carboxylic acids which are ethylenically unsaturated in the alphabeta position and which have three to five carbon atoms, aldehydes ethylenically unsaturated in the alpha-beta position and having three to five carbon atoms, aromatic hydrocarbons having one benzene ring, and linear branched and cyclic ethylenically unsaturated hydrocarbons having one to four carbon to carbon double bonds and two to fifteen carbon atoms. Specified dienes are butadiene, isoprene, 2,3-dimethylbutadiene, 2-ethylbutadiene, pentadiene, hexadiene, cyclopentadiene, cyclohexadiene and vinylcyclohexene-1-up to 40% of comonomers, e.g. styrene, alpha-methyl styrene, vinyltoluene, and/or linar aliphatic triene, e.g. hexatriene-1,3,5, or 3-methylheptatriene, 1,3,5- or octatriene-1,3,6 may also be present. Boron fluoride or an addition complex of boron fluoride are specified boron compounds while aluminium halides may additionally be present. Polymerization may take place in solution, batchwise or continuously. The products may be oily or elastomeric products having almost exclusively 1,4-structure, the fraction having cis, 1,4-structure preponderating are obtained.ALSO:A catalyst composition for polymerising 1,3-dienes comprises (A) a compound containing zerovalent nickel and (B) a fluorine compound of boron - no organometallic compound of metals of groups IA, IIA, or IIIA being present. The nickel compound may contain one to four ligands consisting of carbon monoxide, triaryl phosphines, arsines, and stilbines, esters of phosphoric acid with alkanols of 1-10 carbon atoms cycloalkanols and phenols having up to 10 carbon atoms, alkyl and aryl isonitriles, pyridine, dipyridyl, o-phenanthroline, nitriles of mono and di carboxlic acids which are ethylenically unsaturated in the alpha-beta position and have three to five carbon atoms, aldehydes ethylenically unsaturated in the alpha-beta position and having three to five carbon atoms, aromatic hydrocarbons having one benzene ring and linear, branched and cyclic ethylenically unsaturated hydrocarbons having one to four carbon to carbon double bonds and two to fifteen carbon atoms. Lists are given. Examples use triphenylphosphine nickel tricarbonyl, nickel tetracarbonyl, nickel-(o)benzene, nickel(o)-cyclododecatriene (1,5,9) and nickel-bis-acrylonitrile. Boron fluoride or an addition complex of boron fluoride are specified boron compounds while aluminium halides may additionally be present.

    Abstract: A slow-release fertilizer is produced by coating fertilizer granules with 2-20% of a quick-drying isomerized polyene oil and drying the coating. The fertilizer may be a PKN fertilizer or urea. The granules may have a particle size of 2-4 mm. The polyene may be derived from isoprene, piperylene, cyclopentadiene, cyclohexadiene-1,3, butadiene, 3-methylpentatriene-1,4,6, or n-decatriene,-1,5,9. Copolymerization may be effected with ethylene, propylene, butylene, isobutylene, vinylacetylene, styrene, or acrylonitrile. Isomerization may be effected in the presence of a transistion metal. The oil may have a molecular weight of 500-40,000. It may contain other polymers not capable of further polymerization, e.g. polystyrene or polyacrylonitrile, or their monomers. The oil may be sprayed on to granules heated by hot air at a temperature of up to 300 DEG C. in a rotating drum. A catalyst, e.g. cyclohexanone peroxide, may be present. A plurality of coatings may be applied.
