-
, (2008/06/13)
Disclosed are x-ray contrast compositions for oral or retrograde examination of the gastrointestinal tract comprising an x-ray producing agent of the formula or a pharmaceutically acceptable salt thereof STR1 wherein Z is H, halo, C1 -C20 alkyl, cycloalkyl, lower alkoxy, cyano, where the alkyl and cycloalkyl groups can be substituted with halogen or halo-lower-alkyl groups; R is C1 -C25 alkyl, cycloalkyl, or halo-lower-alkyl, each of which may be optionally substituted with halo, fluoro-lower-alkyl, aryl, lower-alkoxy, hydroxy, carboxy, lower-alkoxy carbonyl or lower-alkoxy-carbonyloxy; (CR1 R2)p -- (CR3 =CR4)m Q, or (CR1 R2)p -- C=C--Q; R1, R2, R3 and R4 are independently lower-alkyl, optionally substituted with halo; x is 1--3 y is 1--4; n is 1--5; m is 1--15; p is 1--10; and Q is H, lower-alkyl, lower-alkenyl, lower-alkynyl, lower-alkylene, aryl, or aryl-lower alkyl in a pharmaceutically acceptable carrier comprising a cellulose derivative.
Pesticide-polymer systems prepared from vinyl monomers
-
, (2008/06/13)
Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
