摘要：NOVELTY - Side-chain grafted sulfonic acid copolymer (I), is new. USE - Side-chain grafted sulfonic acid copolymer (I) used as comb-type copolymer for preparing high-concentration coal water slurry (claimed) and used for disposing the high concentration coal water slurry. ADVANTAGE - Side-chain grafted sulfonic acid copolymer (I) improves the pumping capacity and the storage stability of the coal water slurry, has simple process and low cost, reduces the viscosity of the slurry and improves the fluidity and stability of the coal water slurry. DETAILED DESCRIPTION - Side-chain grafted sulfonic acid copolymer of formula (I), is new. An INDEPENDENT CLAIM is included for a method for preparing side-chain grafted sulfonic acid copolymer of formula (I). m, n=integer, where m and n are more than 7 and less than 24.
