| titleOfInvention | Water-swellable friction reducing composition |
| abstract | A water-swellable friction reducing composition that does not swell at neutrality but swells in an alkaline region. SOLUTION: To 346 parts of a 50% strength vinyl acetate resin elastomer solution dissolved in acetone, 145 parts of toluene and 145 parts of methyl ethyl ketone (MEK) are added as solvents, and carboxymethylcellulose calcium (CMC-Ca) is stirred with a dissolver. 177 parts, 172 parts bentonite, 5 parts rust preventive agent and 10 parts fine particle silica were added and sufficiently stirred to obtain a water-swellable friction reducing composition. This water-swellable friction-reducing composition has a swelling ratio as low as 2.0 times when immersed in fresh water (around pH 7), but has a swelling ratio of around 15 times when immersed in an alkaline solution at pH 14. .
