    摘要: Dicarbamic acid diesters of the formula ##STR1## in which R represents C.sub.1 - C.sub.4 -alkylene which is optionally substituted by one or more halogen atoms, and R.sub.1 and R.sub.2 independently of one another represent C.sub.1 - C.sub.4 -alkyl which is optionally substituted by halogen atoms or together with the oxygen atoms and the phosphorus atom form a 5-membered to 7-membered heterocyclic structure, R.sub.3 is hydrogen, hydroxymethyl or C.sub.1 - C.sub.4 -alkoxymethyl and R.sub.4 represents a divalent radical, with at least 2 carbon atoms, which is free from hydroxyl groups, and of which the two bonds must start from different carbon atoms, and wherein the phosphorus content of the diester is more than 5 % by weight, are suitable as flameproofing agents for textile materials, paper and plastics.
