Wherein Y represents -OH and O-R1 and Y and R2 together represent a single bond of an imide ring. X represents either OR -O-. R1 represents the same or different hydrocarbon radicals containing from about C6 to about C36 carbon atoms selected from the group consisting of normal chain alkyl, branched chain alkyl, cycloalkyl and alkylaryl radicals. R2 represents H or the same or different hydrocarbon radicals containing from about C1 to about C30 carbon atoms selected from the group consisting of normal chain alkyl, branched chain alkyl, cycloalkyl, and alkylaryl radicals wherein the sum total of carbon atoms represented by R1 and R2 is not greater than C36 (when X O, or an imide nitrogen,R2 does not exist). R3 represents either hydrogen, methyl, ethyl or phenyl. R4 represents either hydrogen or methyl, which compounds are particularly useful as thickening agents for solutions of high ionic strength.
Abstract:
Improved padded brassieres in which the padding layer within the cup structure includes a batting of fibers formed together into a cohesive fibrous web, the batting having a plurality of areas devoid of fibers to provide a patterned openwork structure. The open areas are typically in the range of approximately 1/32 to 1/4 of an inch in length and width, arranged in rows of predetermined linear alignment to provide an aesthetic arrangement having porosity, strength, integrity and excellent drapable characteristics.
Abstract:
A system for sustained release of phenolic material into a fluid from phenolic complexes of water-insoluble, but water-swellable crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules. The complexes, which are particularly suited for use in situations wherein fluids containing phenolic materials in limited quantities are desired, and are provided by leaching a limited amount of phenolic material from the complex by contacting the porous granules in a container, such as in a canister or column which is used to treat liquids or water.
