    Abstract: Cyclo octylamine is produced by reacting at 5-25 DEG C cyclo-octene with HCN in presence of 75-98% aqueous sulphuric acid, these three reagents being in a molar ratio of 1:2-15: 1.5-2, there being constantly maintained in the reaction mixture at least 2 moles of HCN per mole cyclo-octene, and saponifying the N-cyclo-octylformamide formed.

    Abstract: The present invention relates to a process for the preparation of a hard foam containing urethane groups or urethane and isocyanurate groups by the polyisocyanate polyaddition process, by reacting a) a polyoxypropylene- or polyoxyethylene-polyoxypropylene-polyol containing secondary hydroxyl groups, having a functionality of from 3.5 to 4.3, a hydroxyl number of from 350 to 650 and a viscosity of from 500 to 2,500 mPa 23 .degree.C and prepared by anionic polymerization of 1,2-propylene oxide or ethylene oxide and 1,2-propylene oxide onto an initiator molecule mixture containing, based on the total weight, a1) from 40 to 80% by weight of a hexanetetrol, a2) from 1 to 30% by weight of a hexanetriol, a3) from 0 to 35% by weight of glycerol and a4) from 0 to 15% by weight of sorbitol or mannitol, or a mixture thereof, b) optionally, a low-molecular-weight chain extender and/or crosslinking agent with c) an organic, modified or unmodified polyisocyanate; in the presence of d) a blowing agent, e) a catalyst and, optionally, f) assistants and/or additives, and novel polyoxypropylene-polyols and polyoxyethylenepolyoxypropylene-polyols which can be used for this purpose.

    Abstract: Polymerizable, mouldable compositions comprise (1) 2-80 parts by weight of a butadiene polymer containing polymerizable ethylenically unsaturated groups and (2) 100 parts by weight of a liquid organic monomer containing polymerizable ethylenically unsaturated groups, at least 75% by weight of component (2) being the acrylic acid ester of tricyclo - [5,2,1,02,6]-decene - (3) - ol - (9). Component (1) may be butadiene homopolymer, particularly the 1,4-polymer; or a copolymer of butadiene with, for example, styrene, a -methyl-styrene, N-vinyl-pyridine and/or acrylonitrile, particularly a copolymer in which the butadiene units are 1,2-linked. Additional monomers which may be included in component (2) can be, for example, those mentioned above in the butadiene copolymers. The compositions may include a polymerization inhibitor, e.g. t-butylhydroquinone or t-butylpyrocatechol; a filler or reinforcing agent, e.g. a glass fibre mat; a pigment; a flame retardant, e.g. a chloroparaffin and tri-(b -chloroethyl) phosphate (stabilized with an epoxidized monoester of glycerol and versatic acid). The compositions are moulded and polymerized in the presence of an initiator such as cyclohexanone peroxide or benzoyl peroxide in combination with a metal salt, e.g. cobalt naphthenate or amine, e.g. dimethylaniline, accelerator.ALSO:The acrylic acid ester of tricyclo-[5,2,1,02,6]-decene -(3)-ol-(9) is prepared by reacting excess acrylic acid with dicyclopentadiene in the presence of BF3 and hydroquinone, firstly at 40 DEG C. and subsequently at 65 DEG C. After removal of the excess acid, washing and extracting, the ester product is distilled in vacuo in the presence of phenothiazine.

    Abstract: Tetrahydrodicyclopentadienylene diamine is prepared by reacting dicyclopentadiene with hydrocyanic acid and sulphuric acid in two stages, the first stage being carried out at - 5 DEG to + 20 DEG C. using 1 to 3 moles of sulphuric acid, while the second stage is carried out at a temperature of 0 DEG to 30 DEG C., such an amount of sulphuric acid being added that the total amount of sulphuric acid used is from 3 to 6 moles per mole of dicyclopentadiene, but at least one mole more than in the first stage, the reaction mixture then being hydrolysed and the diamine product being recovered by conventional methods. The whole of the hydrocyanic acid may be present in the first stage. Both the temperature and the strength of the sulphuric acid in the first stage are preferably lower than those in the second stage.
