Abstract: FIELD: adhesives and glued articles. SUBSTANCE: invention relates to manufacturing layered panels, or so called "sandwich panels", suitable as ornamental and heat-insulation materials. Manufacture of processing- strong sandwich panels fit to be transported to final hardening place for a short period of time (during which time glued connection should be unbroken in case of using layers with glossy finish) is achieved by employing glue composition consisting of A and B components. Component A is prepared by preliminarily mixing polyester obtained by polycondensation of aliphatic dicarboxylic acid having 4-6 carbon atoms with a polyol selected from ethylene glycol, diethylene glycol, triethylene glycol, 1,4-butanediol, glycerol, trimethylolpropane, and their mixture, catalyst selected from diazobicyclooctane, tertiary amines, organotin compounds, and their mixtures, and optionally toluene or ethyl acetate. Component B is prepared by preliminarily mixing polyisocyanate and ethyl acetate solution of product obtained by condensation of poly(butylene glycol adipate), butylene glycol, and toluylene diisocyanate. Glue composition is laid on inner side of lower layer, onto which middle layer (foamed polystyrene, foamed polyurethane, or glasswool) is further placed, whereupon glue composition is laid on open surface of middle layer, covered by top layer, and thus obtained preform is rolled.

Abstract: FIELD: polymers. 
     SUBSTANCE: invention relates to preparing polymeric cation-exchange-resins and methods for preparing a water-soluble high-molecular nitrogen-containing cation-active polymer used as a coagulating agent for treatment of sewage, fixing agent for gluing substances, antistatic agent for fibers and fixing agent for dyes. Invention describes a method for preparing a water-soluble polymeric cation-exchange resin by the copolymerization reaction of N,N-dimethyl-N,N-diallylammonium chloride with sulfur dioxide in the presence of radical-forming initiating agent. Method involves the copolymerization reaction that is carried out at temperature 55-90 C in the mole ratio N,N-dimethyl-N,N-diallylammonium chloride : sulfur dioxide = 1:1 in the presence of an initiating agent taken in the amount 0.1-1.0 wt.-% of monomer mass. Potassium persulfate or ammonium persulfate is used as an initiating agent up to the conversion of parent co-monomers 80-95 wt.-% and copolymerization reaction is continued in the presence of adduct formed in interaction of acetone and hydrogen peroxide only in the mole ratio acetone : hydrogen peroxide = 2-(2:1). Except for, mixing copolymers is carried out at temperature 15-25 C. Carrying out the process under relatively mild conditions with partial replacing ammonium (potassium) persulfate for hydrogen peroxide, or carrying out the polymerization process in the presence of adduct formed in interaction of acetone and hydrogen peroxide only allows preparing product with high degree of polymerization being without gel formation and its precipitating. Method exhibits high technological effectiveness and provides preparing the effective polymeric cation-exchange resin with relatively high viscosity and, therefore, with high molecular mass of polymer. 
     EFFECT: improved preparing method, valuable properties of cationite.
