Artificial baits are disclosed which slowly release a fish attactant into the water upon use. Said artificial baits comprise a water-soluble cellulose ether, a plasticizer therefore and an attractant for fish or other sea-living animals. Said artificial bait can be employed in a variety of forms suitable for sport fishing, commercial fishing, lobster trapping, and the like.

Artificial fish baits with sustained release properties

Thickening compositions are disclosed which impart highly pseudoplastic behavior to aqueous compositions containing same. The compositions of this invention comprise a water-soluble high molecular weight organic polymer and a water-insoluble, water-dispersible and water-swellable organic polymer which is compatible with the water-soluble polymer. Aqueous solutions, suspensions or emulsions containing the thickeners of this invention exhibit very high sensitivity to applied shear.

Highly pseudoplastic polymer solutions

Safety packages are prepared for transportation of methanol wherein ethyl cellulose having from about 45 to 46.5 weight percent substitution is employed as a sorbent.

Method and material for the restraint of polar organic liquids

Novel ternary hydroxyethylhydroxypropylmethylcellulose ethers are disclosed. These ethers have lower cloud points than most cellulose ethers having hydroxyethoxyl substitution and exhibit return cloud points which are approximately the same as their cloud points.

Water-soluble, ternary cellulose ethers

Novel compositions comprise homogeneous mixtures of liquid carbon dioxide and an anhydrous lower alkanol gelled to a viscosity of at least 10 centipoises with a hydroxypropyl methylcellulose having a methoxyl degree of substitution of from 0.2 to 1.0 and a molar substitution of hydroxypropoxyl of at least 1.2. The compositions are employed in a method of treating a subterranean formation penetrated by a wellbore by injecting same under pressure down the wellbore and into the formation to stimulate production of natural gas or petroleum.
