Abstract:
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.
Abstract:
The invention relates to the use of at least one polymer which is different from polyethylene imine and which contains primary and/or secondary amino groups in cosmetic preparations for reducing the body odor caused by the formation of saturated and unsaturated C6-C12 aldehydes from the unsaturated fatty acids of the skin and/or the scalp.
Abstract:
The present invention relates to a composition comprising an active ingredient soluble in water at 20°C at no greater than 10 g/L, and a hyperbranched polyester linked to a polar polymer comprising a polycondensate or a polymer comprising ethylene unsaturated monomers. The invention further relates to said hyperbranched polyester and to a method for the production thereof. The invention further relates to the use of the hyperbranched polyester for solubilizing the active ingredient in aqueous compositions.
Abstract:
The present invention relates to seed treatment compositions comprising active ingredient and hyperbranched polymer. The hyperbranched polymer is used as seed coating agent, especially as a binder to promote adhesion of the active ingredient(s) to the seeds. The present invention also relates to methods of treating seed with such a composition.
Abstract:
The invention relates to the use of highly functional, highly branched polyetheramine polyols for coating substrates such as metal surfaces or plastic components, allowing an improved adhesion of additional coats.
Abstract:
The invention relates to a method for producing highly functional polyetherols by reacting at least one trifunctional or higher functional alcohol and optionally further difunctional and/or monofunctional alcohols and/or modifying reagents with the help of acidic catalysts, the trifunctional or higher functional alcohol not being glycerol. The invention further relates to highly functional polyetherols that can be obtained by said method and to the use of said highly functional polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, microcontainers or nanocontainers for biolo-gically active substances, for example for medical active substances, biocides, herbicides or fungicides, as pigment dispersants, additives in printing inks, as components for producing polyaddition or polycondensation polymers or for treating seeds.
Abstract:
Procedimiento para la impresión de substratos, en el que se transfiere a un molde de impresión una tinta deimprenta o un esmalte de imprenta, que comprende al menos disolvente y agente aglutinante, el molde de impresiónprovisto de tinta de imprenta o esmalte de imprenta se pone en contacto con un substrato, y de este modo la tinta deimprenta o el esmalte de imprenta se transfiere del molde de impresión al substrato, tratándose en el caso de almenos uno de los agentes aglutinantes de un poliol de polieteramina con un peso molecular promedio en número Mnde 500 a 50000 g/mol, que presenta, además de grupos éter incorporados en el esqueleto de polímero, así comogrupos amino secundarios y/o terciarios, al menos grupos funcionales en posición terminal y/o lateral.
