摘要： The invention relates to the use of hyperbranched polymers or oligomers comprising terminal primary and/or secondary amino groups as curing agents for epoxy resins. The invention further relates to a composition containing such polymers or oligomers, an uncured or only partially cured epoxy resin, and at least one optional curing agent for epoxy resins, as well as a cured epoxy resin that can be obtained by curing said components. The invention finally relates to a method for curing epoxy resins. In said method, an uncured or only partially cured epoxy resin is brought to a temperature of 5 to 150°C or is exposed to microwave radiation along with at least one polymer or oligomer according to the definition above and at least one optional conventional curing agent for epoxy resins.

摘要： The invention relates to a method for producing highly-branched melamine polymers, according to which melamine with 1.5 to 4 mol of one or several diamines or polyamines per mol of melamine, said diamines or polyamines having at least two primary amino groups, is reacted in the presence of an acidic catalyst. According to the invention, up to 25 mol % of the diamines or polyamines can have three or more primary amino groups and up to 50 mol % of the diamines or polyamines can be substituted by amines with only one primary amino group.

摘要： The invention relates to a method for reducing the emission of formaldehyde in wood materials by applying nitrogen-containing compounds. Said method is characterized in that (i) a mixture containing at least one polyamine and optionally up to 20 percent by weight of urea relative to the mixture is applied to the wood material; (ii) polyamine is applied onto or into the chip cake or fiber cake; (iii) polyamine is applied to the coating substrate used for finishing the surface; and/or (iv) polyamine is applied to the exposed points. The polyamines have a minimum molecular weight of 500 g/mol while being provided with at least 6 primary or secondary amino groups.

摘要： A process for preparing etherified melamine-formaldehyde condensates, in which a methylolation of melamine is first performed with a formaldehyde component in a molar ratio of 1:6 to 1:15, preferably at a pH of > 7. This is followed by an etherification of the resulting hydroxy­methylation intermediate in the presence of a C1-C20-alcohol, preferably of a C1-C6-alcohol, more preferably of a C1-C4-alcohol, at a pH of 9.5 is established before, during and/or after the distillation. According to the invention, this is followed by several hydroxymethylation, etherification and distillation steps, in order to achieve an etherified melamine-formaldehyde condensate which features a high degree of hydroxymethylation, a high solids content and a low viscosity.
