FIELD: chemistry.
SUBSTANCE: invention relates to water-based molded polymer product for producing a fluid for fracturing a formation during drilling and a method for manufacturing it. Water-based molded polymer article has a dispersion structure in which the hydrolysable polymer is dispersed in a matrix of a water-soluble polymer. Hydrolysable polymer is dispersed in the matrix in granular or fibrous form. Matrix of the water-soluble polymer is contained in an amount of 10 to 150 parts by weight based on 100 parts by weight of the hydrolyzable polymer.
EFFECT: molded polymeric article can simplify mixing operation with water without degrading the properties of the hydrolyzable polymer.
