Mixture of hydroxypropylcellulose and poly(maleic anhydride/alkyl vinyl ether) as a hydrocolloid gelling agent

摘要: In one embodiment this invention provides a fluid composition which comprises an aqueous medium is thickened with synergistic viscosity mixture of hydroxypropylcellulose and poly(maleic anhydride/alkyl vinyl ether) as novel hydrocolloid gelling agent. An present agent applicable vehicle for explosive slurries, printing pastes, paint formulations, adhesives, the like. A thixotropic uniquely adapted use hydraulic in well-drilling operations secondary oil gas recovery from subterranean formations.
