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.

n: also called copolymer of vinyl acetate and maleic anhydride, (CHCO)2O, clear crystallisation.

n: Usually used as high temperature mud thinner,which is made by sulfonated styrene and maleic anhydride.

n: The copolymer of maleic anhydride and vinyl acetate by catalytic reaction in the particular condition,which can be used as coagulant.
