摘要： The invention relates to a hardenable adhesive, which contains as effective components at least one polyol and one polyisocyanate and/or their prepolymers as well as additionally conventional additives, such as, accelerators, gluing auxiliaries, pigments and/or fillers. It is characteristic of the inventive adhesive that it contains, as a polyol, the reaction product of a novolak of average molecular weight from 300 to 1200 with an oxirane of the general formula ##STR1## in which R.sup.1 is hydrogen, or an optionally halogenated hydrocarbon group with 1 to 4 carbon atoms or the --CH.sub.2 OR.sup.2 group, in which R.sup.2 represents an alkyl or an alkenyl group, the R.sup.1 group within the polymeric molecule being the same or different, there being added, on the average, 1 to 7 moles of the oxirane per hydroxyl group of the novolak, and the polyol and the polyisocyanate being present in such a ratio that 0.95 to 1.25 isocyanate groups of the polyisocyanate correspond to one hydroxyl group of the polyol. The inventive adhesives are liquid, adhere well to plastic surfaces and have a high peel strength. They are resistant to the effects of water and moisture.

摘要： The invention relates to a process for flexibilizing epoxide resins by the addition of polymers which contain carboxyl groups by adding to the epoxide resins before they are cured, copolymers which are obtained by the conventional polymerization of:(a.sub.1) 40 to 87 weight percent of one or several alkyl esters of acrylic and/or methacrylic acid with 1 to 8 carbon atoms in the alkyl radical,(a.sub.2) 10 to 40 weight percent of vinyl acetate and/or acrylonitrile,(a.sub.3) 1 to 20 weight percent of acrylic, methacrylic and/or itaconic acid,(a.sub.4) 1 to 5 weight percent of glycidyl acrylate and/or glycidyl methacrylate, and(a.sub.5) 0 to 35 weight percent of acrylic and/or vinyl monomers, which are different from the monomers a.sub.1 to a.sub.4in the presence of a regulator, which contains mercapto groups and has at least one carboxyl group, and whereinthe copolymers have an average molecular weight of 1,000 to 3,000 as measured in a vapor pressure osometer, andthe polymers are added in such amounts that 1 to 60 mole percent of the epoxide groups react with the carboxyl groups of the copolymer.The viscosity of the uncured epoxide resin is increased only moderately by the addition of the modifier. The cured, modified epoxide resins have a higher degree of elastification and can be used as adhesives which adhere well to contacting surfaces and as resins, for example, for the production of prepregs.

C. in methyl acetate, and(b) one or more polyisocyanates and/or their partial reaction products with polyols, the molecule having on the average at least 2 isocyanate groups,components (a) and (b) being present in a ratio such that one hydroxyl group of component (a) corresponds to 1 to 1.5 isocyanate groups of component (b), as well as, if necessary, the usual additives, such as, accelerators, gluing auxiliaries, pigments and fillers. The adhesive can be cured at temperature of 80.degree. C. and less, without decreasing the adhesion. In so doing, the moisture resistance and the resistance towards weathering are maintained. The adhesive is therefore particularly suitable for the manufacture of skis.

摘要： The invention relates to a curable adhesive based on a reactive acrylate and/or methacrylate copolymer. The reaction principle, on which the curing of the adhesive is based, is the reaction of the hydroxyl groups of the .omega.-hydroxyalkyl esters of acrylic and/or methacrylic acids with the isocyanate groups of the polyisocyanates or their partial reaction products with polyols. The inventive adhesives can be used without solvents or with only a slight content of organic solvents. They adhere well to plastic and metal surfaces, even when exposed to the effects of water or water vapor. The best values for the drum peel strength are obtained from acrylic copolymers whose molecular weight falls in the range of 1,000 to 3,000.

摘要： A process for making carrier sheets of paper, treated with aqueous solutions of heat-hardenable, aminoplast condensation resins, such as, the reaction products of melamine, urea, thiourea, and like aminoplast constituents with formaldheyde, in which the treated sheet is stretched, as by passing it over broad-drawing rollers while it is in a warm-deformable condition (at a temperature between about 80.degree. to 130.degree.C), transversely with respect to the grain of the paper and, if desired, longitudinally with respect to the grain of the paper, and the treated stretched sheet is then cooled to a temperature of about 30.degree.C by blowing with air or passing the same over cooling rollers. The treated sheet may be stretched after it has passed through a heated drying channel, to dry and procondense the heat-hardenable aminoplast condensation resin, and before the temperature has dropped below that at which the sheet is no longer in a warm-deformable condition or the sheet may be cooled after passage through the heated drying channel and then reheated to a warm-deformable condition. The treated, stretched sheets of the present invention are pressed on wood panels in a heated hydraulic press and preferably in a heated short-cycle press.
