    Abstract: The compounds of the formula (I) (I) in which X denotes CH2, O, S or NR6, R1 denotes alkyl, cycloalkyl, alkenyl, (substituted) phenyl, or (substituted) naphthyl, R2 and R3 denote alkyl, alkenyl or phenyl, or R2 and R3 together denote an alkylene chain, R4 denotes -H, -CN, -CCl3, -C 3BOND CH, alkyl, F, or -C(S)-NH2, R5 denotes pyridyl, furyl, thienyl, phthalimidyl, di(C1-C4)alkylmaleinimidyl, thiophthalimidyl, dihydrophthalimidyl or tetrahydrophthalimidyl, which may all be substituted, or substituted phenyl, or R4 and R5-together with the carbon atom bridging them-denote an optionally substituted indanyl, cyclopentenoyl or cyclopentenyl radical, with the proviso that compounds of the formula I in which R1 denotes phenyl which is substituted in the para-position by (C1-C4)alkoxy, halogen or (C1-C4)alkyl; R2 and R3 denote CH3; X denotes O; R4 denotes H and R5 denotes 3-phenoxyphenyl or (4-fluoro-3-phenoxy)phenyl being excepted, have advantageous insecticidal, acaricidal and nematocidal properties.

    Abstract: Synthetic materials are stabilised against ultra-violet light by addn. of a cyclic diphosphite of formula: where X is a 2-6C alkylene, opt. substd. by halogen, alkoxy or carbalkoxy, or a phenylene opt. substd. by >=1 halogen atoms, 1-5C alkyl or carbalkoxy, and Y is alkylene a 2-12C alkylene ether a phenylene opt. substd. by >=1 halogen atoms, 1-5C alkyl or carbalkoxy, or an alkylene-arylene in which the arylene gp. has 6C or 12C and the alkylene is 1-3C. (I) have better stabilising properties than known ultra-violet absorbents contg. OH gps. The synthetics are esp. (co)polymers of ethylene, propylene, butene and 4-methyl-1-pentene, or polystyrene.
