摘要:
An organophosphorus compound, useful in controlling pests, having the formula wherein R is C 1 -C 3 alkyl or phenyl, R' is hydrogen or R and R 1 together form a 1,3-butadien-1,4-diyl group optionally substituted with a methyl or chloro group, or R and R 1 together form a 1,2-ethenediylthio group wherein sulfur is attached to carbon; R 2 is hydrogen or halogen; X is oxygen or sulfur; R 3 is C 1 -C 3 alkyl; and R 4 is C 1 -C 3 alkoxy or propythio and their hydrochlorides, with the proviso that if R is phenyl, R 3 is methyl and R 4 is methoxy is disclosed. Compositions containing the active compound and methods of controlling pests, are also disclosed.

Superior herbicial compounds, and compositions thereof, are provided having the formula: wherein X and X' are the same of different and are chloro or fluoro.
摘要:
A layered sheet construction suitable after processing for use as a relief printing plate is provided. The sheet is made of a photosensitive layer comprising an elastomeric polymer, between 5 and 30 phr of an ethylenically unsaturated compound and between 0.1 and 5 phr of a photoinitiator activatable by actinic radiation; a base layer immediately adjacent to said photosensitive layer capable of supporting a relief image after processing; having the same or a different composition than said photosensitive layer. The sheet is bonded to an open or closed cell foam layer having a thickness between 0.25 mm and 6.35 mm. Said foam has a recovery rate of at least 80%, a compression value between 0.076 mm and 0.76 mm and a density of between 32 and 801 kg/m 3 and is bonded to a dimensionally stable supporting layer.
