    Abstract: The prodn. of polyalkyl-1-oxa-diazaspirodecane cpds. of formula (I) comprises reacting a cpd. of formula (IV) with an epihalohydrin of formula (V) in the mole ratio of (1:1)-(1:10) in inert solvent and in the presence of alkali hydroxide (AOH) as the sole catalyst and then (for n > 1) heating the resulting epoxide (VI) at 100-240 degrees C; after the reaction, sufficient water is added to form two phases. The AOH consists of 1-20 moles solid alkali metal hydroxide or a mixt. with water in the wt. ratio of (1:9)-(9:1). n = 1-50; Y = a gp. of formula (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 = H or 1-5 C alkyl; 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 = m > 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.
