Abstract: A process for the continuous preparation of epsilon -caprolactam by Beckmann rearrangement of cyclohexanone-oxime, dissolved in a solvent which is inert toward oleum and is immiscible with oleum and water, at an elevated temperature, with removal of the heat of rearrangement by evaporation of the solvent, wherein oleum containing caprolactam is circulated successively through a conveying zone, a mixing zone, a boiling zone and a separating zone, upstream of the conveying zone oleum is added at the rate at which it is consumed, in the mixing zone cyclohexanone-oxime dissolved in solvent is added under turbulent conditions, in the boiling zone the heat of rearrangement is removed in a conventional manner by evaporating the solvent and recycling the condensate, and in the separating zone the reaction mixture is separated into a solvent phase, from which solvent is withdrawn at the rate at which the phase is formed, and a caprolactam-containing oleum phase, which is removed at the rate at which it is formed.

Abstract: High molecular weight linear polycarbonates are prepared by continuous condensation of organic dihydroxy compounds and phosgene in two reaction zones, a mixture of an aqueous-alkaline solution of the organic dihydroxy compound and an aqueous catalyst solution being introduced at the rate of from 1 to 50 meters per second and the phosgene at the rate of from 30 to 300 meters per second into the first reaction zone and condensed, an organic solvent being incorporated into the resultant reaction mixture containing oligomer and polycarbonate and the condensation of the aqueous-organic reaction mixture carried to completion in the second reaction zone by the two-phase interfacial method.

Abstract: This invention relates to a process for preparing cellular polymers having urethane groups, isocyanurate groups, or both. The cellular polymers are prepared by reacting an organic polyisocyanate with certain polymer dispersions in the presence of a blowing agent. The polymer dispersions comprise (a) as a continuous phase, a polyol having a functionality of 2 to 8 and a hydroxyl number of 150 to 700; and (b) as a dispersed phase, an organic compound having (a) at least one Zerewitinoff active hydrogen atom, (b) a melting point of 30 DEG C. to 260 DEG C., and (c) a molecular weight of 178 to 100,000.

Abstract: The parent patent concerns copolyamides (I) with K values of 35-70 (1% soln. in 96% H2SO4 at 20 degrees C), obtd. by melt condensn. at 180-300 degrees C from 5-18 (wt.)% hexamethylenediamine adipate (II) and 95-82% salt (III) of piperazine and mixts. of decane-1,10-dicarboxylic acid and azelaic acid in 70:30 to 95:5 molar ratio, opt. in the presence of traces of a monocarboxylic acid as mol. wt regulator. In this patent of addn. the novel feature is that a salt (IV) of adipic acid with a 5-20, pref. 6-15C (cyclo)aliphatic prim. diamine is used instead of (II). (I) are specified for dressing artificial leather with a plasticised PVC surface. (I) form stable solns. in the usual solvent mixts., adhere firmly and permanently to the surface, have good feel, gloss and mechanical properties and retard plasticiser and dyestuff migration.

Abstract: Thermoplastic nylons are stabilized with copper compounds and synergistic halides by incorporation of from 0.1 to 10% of a concentrate of nylon, copper bromide or iodide and calcium bromide, zinc bromide or magnesium bromide. The stabilized nylons may be thermoplastically processed to give semimanufactures or films.

Abstract: Stabilisation is achieved against heat and oxidn. by adding aziridines (I) (where R is a 1-18C aliphatic gp. opt. substd. by Oh, CN, carbamido or carboxyalkyl. R can also be alkylene, aryl, cycloalkyl or acyl. No.n= 1-3). Stabiliser quantity may be 0.01-5 (0.1-1) wt. % wrt. polymer. Polybutylene terephthalate used has relative viscosity 1.3-2 (1.5-1.7), measured in 0.5% soln. at 25 degrees C in phenol/o-dichlorobenzene mixt. having wt. ratio 3:2. Injection-moulded articles and films resist heat-ageing.
