摘要： Water-soluble, crosslinked nitrogen-containing condensation products, the viscosity of which, in aqueous solution, increases with increasing temperature, are obtained by reacting a block copolymer of the formula: ##STR1## x is from 50 to 250, y is from 20 to 100, the ratio of x to y is from 6.5:1 to 1:15, with compounds having at least four basic NH groups in a weight ratio of from 0.8:1 to 30:1. The products are added to aqueous systems, e.g. polymer solutions and polymer dispersions, to improve the viscosity characteristics.

摘要： A two-component curable epoxy resin system is disclosed. The resin system includes an epoxy resin component containing at least 80% by weight of a polyglycidyl ether of a polyphenol. The system also includes a hardener mixture containing mainly polyethylene tetraamines. The system includes one or more of i) alkali metal salts, ii) carboxylic acid-, carboxylic anhydride- or carboxylic acid ester-substituted phenol compounds, iii) an amino as a catalyst. The system has beneficial curing characteristics that make it useful for producing fiber-reinforced composites in a resin transfer molding process.

摘要： The present invention relates to curing agents for epoxy resins including an alkylated polyethyleneimine. These curing agents have high functionality and a high content of secondary amino groups. Together with epoxy resins, they cure surprisingly quickly and without blushing effects even under humid and cold conditions to form films having very high cross-linking density. They are suited for coatings with high resistance requirements.
