Abstract
A process for obtaining cell plastics from epoxy compounds with more than one epoxy group in the molecule, with the addition of di and polyisocyanates, pore regulators, liquid porogens and, optionally, polyphenols, by curing with the aid of acids of lewis and/or acidic phosphoric compounds, characterized in that diisocyanates or polyisocyanates hardly soluble in it at ambient temperature, possibly covert, with melting points above 40 [deg.] c., preferably above 80 [deg.] c., are added to the mixture to be frothed., and with a particle size of less than 400 μ in a scattered way (Machine-translation by Google Translate, not legally binding)
