Abstract: A derivative of phosphoric acid ester salt or adduct or a mixture thereof is obtained from a reaction product, polycondensed with at least one aldehyde, of at least one polyol phosphoric acid ester with at least one organic nitrogen base. The derivative is advantageously used as a flame-inhibiting and/or intumescent treatment in plastic mouldings, on porous carriers or in paint or coating systems. The production of the derivative or a mixture thereof by reacting at least one polyol with phosphorus pentoxide and reacting the polyol phosphoric acid ester obtained in that way with at least one organic nitrogen base forming a phosphoric acid ester salt or adduct, is characterized in that the amount of phosphorus pentoxide required for the esterification operation is suspended in an amount of the ester or ester mixture to be produced, then at a temperature in the range of 20–180° C.

A strip of material is cut into lengths corresponding to the later periphery of the flange sleeve. The strip section thus arising is rolled to form a hollow cylindrical sleeve with an open butt joint and a collar is placed around one or two sides. The open butt joint is expanded in the region of the collar to form a V-shaped slit. One or several recesses are made in the region of the later open butt joint on one or two of the longitudinal edges of the strip section.
