n: any of several substances - usually organic compounds of high molecular weight-that, when added in low concentrations to a bentonite or to certain other clay slurries, will increase the viscosity of the system. See low-solids mud.

n: The material increasing viscosity by adding into the clay slurry.

a drilling additive to increase the viscosity of water based muds gelled with bentonite.

n: a substance formed when two or more substances polymerise at the same time to yield a product which is not a mixture of separate polymers but a complex having properties different from either polymer alone. See polymer. Examples are polyvinyl acetatemaleic anhydride copolymer (clay extender and selective and selective flocculant),acrylamide-carboxylic and copolymer (total flocculant).

n: The product manufactured by the copolyreaction of two or more element.

a mixture of two or more polymers which polymerize at the same time and with some degree to linking to yield results unlike either polymer used alone.
