  • Patent number: 9200115
    Abstract: A process for continuously preparing copolyamides from lactams and salts of diamines and dicarboxylic acids, in which lactams together with salts of diamines and dicarboxylic acids are passed from the top downward through a vertical polymerization tube at polyamide-forming temperatures, which comprises a) intensively mixing an aqueous solution of lactams with salts of diamines and dicarboxylic acids under elevated pressure which is greater than the vapor pressure of the mixture which arises in a mixing apparatus at a temperature of from 80 to 300° C., b) feeding the mixture thus obtained to a heated helical tube evaporator in which a liquid phase and a vapor phase form at a temperature of from 140 to 300° C.

  • Patent number: 8974591
    Abstract: This invention describes an adhesive composition that forms the basis of a heat-resistant, fire resistant, and water resistant polyurethane adhesive suitable for applications in the manufacture of wood products, and the method of making the adhesive. The wood finger-jointed studs produced using an adhesive derived from this invention can meet or exceed the fire rating of a period of 60 minutes according to ASTM E 119 and ASTM D 7374. The heat resistance of the adhesive is a result of incorporating thermally stable aromatic polyol molecules into the polymeric structures of the wood adhesive system, which is composed of the reaction products of a poly(methylene diphenyl diisocyanate), at least one of a polyether polyol and a polyester polyol; and the aromatic polyol that is a hydroxyl phenol in a preferred embodiment. Furthermore, this novel wood adhesive system possesses high water-resistance, making it suitable for the manufacture of highly durable engineered wood products.

    Abstract: The invention concerns novel anionic polyurethanes with elastic property, that is having an instantaneous elastic recovery ranging between 5% and 100% consisting essentially (a1) of anionic units derived from at least a monomer or polymer compound with sulphonic and/or phosphonic acid function and having at least two functions reactive to labile hydrogen, optionally (a2) non-ionic units derived from at least a non-ionic monomer or polymer compound having at least two functions reactive to labile hydrogen, and (b) units derived from at least a diisocyanate, provided that at least one type of the units (a1) and (a2) is derived from a polymer having a glass transition temperature (Tg) measured by differential enthalpy analysis, less than 10° C. and that said sequences with Tg less than 10° C. represent 20 to 90% of the total weight of the polyurethane. The invention also concerns cosmetic compositions containing the novel anionic polyurethanes with elastic property.

  • Patent number: 6667355
    Abstract: Flame retardants for polymer compositions which are mixtures including triaryl phosphate esters represented by the following formula: where R1-R15 can independently be located in the ortho, meta or para positions on their respective phenol rings and are, independently, H or branched or linear alkyl groups having 3 to 11 carbon atoms and the mole ratio of the alkylate to phenol in the mixtures is at least about 0.77, preferably greater than about 0.81, and most preferably greater than about 0.85. The higher alkylated mixtures of triaryl phosphate esters can be incorporated into polymer compositions alone or in combination with other flame retardants.

  • Patent number: 6313186
    Abstract: A inorganic-organic composite foam having a structure comprising phosphoric acids and a blowing agent for phosphoric acids, wherein the brittleness is improved by urethane prepolymer having NCO groups. The foam is produced by foaming and curing by mixing each component of phosphoric acids, a blowing agent for phosphoric acids, urethane prepolymer having NCO groups, water, and, if necessary, an inorganic filler. A foam of phosphoric acids is inherently brittle, but the brittleness is improved, and flexibility and rebound resilience can be provided. The foam of the present invention is effectively used for the applications, for example, heat insulating materials of external panel or internal panel which require the fire preventive property of train, automobile, housing, building etc.
