| titleOfInvention | Dicarboxylic acids and dicarboxylic acid esters containing a 1,1'-methylene-bis-hydantoin radical |
| abstract | Abstract of the Disclosure Dicarboxylie acids and dicarboxylic acid esters of the formula wherein both R1 each denote hydrogen, alkyl with 1 to 4 C atoms or phenyl, both R2 each denote hydrogen or alkyl with 1 to 10 C atoms and, if the two R2 each denote hydrogen, the two n re-present numbers from 2 to 12 and, if the two R2 each denote an alkyl group with 1 to 10 C atoms, the two n represent numbers from 1 to 12, R3 denotes hydrogen, methyl or ethyl and R4 denotes methyl, ethyl, propyl or isopropyl, are prepared by reacting 1 mol of a 1,1'-methylene-bis-hydantoin of the formula or its disodium or dipotassium salt with 2 mols of a compound of the formula wherein Y1 denotes a chlorine or bromine atom. The dicarboxylic acid compounds are characterized by a high stability to heat and therefore very suitable for the manufacture of polyconden-sates by the melt condensation process. - la - |
