Phosphate esters having the formula RO[-(A).sub.m (B).sub.n ] H wherein A has the structural formula ##SPC1## And B has the structural formula ##SPC2## Wherein the R groups are alkyl radicals, m and n are each integers from 0 to 4 and the sum of m + n is from 1 to about 4, are useful as flame retardants, especially for rigid polyurethane foams.
Bicyclic phosphites are used alone or in combination with other stabilisers for stabilising polyolefines.

Syntheses of the original compact molecular systems were developed and the ways of their practical use were examined. A group of new substances was synthesized on the basis of available penta-erythritol bicyclophosphite and thionophosphate, including respective ammonium salts, phosphocholines, a complex compound of molybdenum, and a hydrophosphoryl compound.
