    Abstract: The prodn. of polyalkyl-1-oxa-diazaspirodecane cpds. of formula (I) comprises reacting a cpd. of formula (VI) with an epihalohydrin of formula (V) in the mole ratio of (1:1)-(1:10), in organic solvent and in the presence of alkali hydroxide (AOH) as the soln. catalyst and then (for n > 1) heating the resulting epoxide (VI) at 100-240 degrees C. The AOH consists of 1-20 moles solid alkali metal hydroxide or a mixt. thereof with water in the wt. ratio of (1:9)-(9:1) and the solvent comprises alcohol(s) and opt. an inert organic solvent. n = 1-50; Y = a gp. of formula (II) or (III) (indices 3 and 4 indicate ring positions in I, with the N atom attached to a CH2 gp. in the propylene-2-oxy gp.); R = H, O, NO gp., 1-12 C alkyl or alkoxy, allyl, 1-22 C acyl, benzyl or 3-12 C cycloalkoxy; R = R = H or 1-5 C alkyl and R = Me; or R = H or 1-5 C alkyl and R + R + attached C atoms = 5-6 C cycloalkyl gp. or a gp. of formula; R , R = H, 1-30 C alkyl or 7-12 C phenylalkyl (opt. substd. with Cl or 1-4 C alkyl); or R + R + attached C atom = 5-18 C cycloalkyl (opt. substd. with up to four 1-4 C alkyl gps.) or a gp. of formula; if n = 1, R is absent, i.e. the O and the terminal CH2 gp. form an oxirane ring; if n > 1, R = H or 1-22 C acyl; or R may be absent in the terminal monomer unit with an oxirane ring present as above; HX = acid residue or a salt thereof with a protic acid; Hal = Cl, Br or I.

    Abstract: In synthetic moulding compositions, especially those based on olefin polymers, which contain phenolic stabilisers and metal ions as catalyst residues, the discoloration at the processing temperature is reduced when they contain triglycerol or ditrimethylolpropane as catalyst inactivators.
