Zusammenfassung:1326968 Drill muds INTERNATIONAL MINERALS & CHEMICAL CORP 17 May 1971 [2 June 1970] 15371/71 Heading E1F [Also in Division Cl] A clay composition for use as a drilling mud or for use in slurry trenching comprises a bentonite or sub-bentonite clay containing minor amounts of (A) a water soluble polyalkylene oxide (e.g. polyethylene oxide) and (B) a water soluble polymer containing carboxyl groups or salts thereof or a polymer anhydride. B may be a copolymer of maleic anhydride and e.g. methyl vinyl ether, an acrylic type polymer or a graft copolymer of acrylic acid with a polyhydroxy compound e.g. sugars, starch or derivatives thereof or polymeric compounds containing hydroxyl groups e.g. polyvinyl alcohol.
