    摘要: Piperidine-spiro-hydrantoin derivatives having the formula ##STR1## wherein X represents oxygen atom or sulfur atom; n is an integer of 1 to 4 inclusive; andR represents, when n is 1, an alkenyl group which may be substituted with halogen, an alkynyl group which may be substituted with phenyl, an aralkyl group which may be substituted with halogen, alkyl of 1 to 4 carbon atoms or halomethyl, a hydroxyalkyl group, an alkoxyalkyl group, an alkenyloxyalkyl group, an acryloxyalkyl group, an alkylthioalkyl group, an acyloxyalkyl group, an epoxyalkyl group, an N-alkyl-substituted aminoalkyl group, an alkoxycarbonylalkyl group, an aryloxycarbonylalkyl group, an aliphatic acyl group, an alkoxycarbonyl group, a phosphino group which is substituted with phenoxy or alkoxy or a phosphinyl group which is substituted with phenoxy or alkoxy,When n is 2, an alkenylene group of 4 to 18 carbon atoms, a dialkyleneether group, an aralkylene group, a bis(acyloxyalkylene) group or an alkylene-bis(oxycarbonylalkyl) group,When n is 3, a tris(acyloxyalkylene) group, an alkane-tris(oxycarbonylalkyl) group or a group of the formula ##STR2## IN WHICH P IS AN INTEGER OF 1 TO 8 INCLUSIVE AND P'S MAY BE THE SAME OR DIFFERENT, AND,When n is 4, a tetrakis (acyloxyalkylene) group.These compounds (I) are useful as stabilizers against photo-and thermal-deteriorations of various synthetic polymers and can be prepared, for example, by reacting the corresponding 3-unsubstituted piperidine-spiro-hydantoin compound with the halide R-(X.sub.1).sub.n in which R and n are as defined above and X.sub.1 is a halogen atom.
