摘要： The present invention provides a sulfonated coal tar distillate salt polymer that is a condensation product of an aldehyde, preferably formaldehyde, and a sulfonated middle fraction obtained during coal tar distillation. The middle fraction includes from about 40% to about 95% by weight naphthalene and from about 5% to about 60% by weight of a plurality of compounds selected from the group consisting of quinoline, indene, biphenyl, indane, acenaphthene, anthracene, phenanthrene, methyl naphthalene, cresol, phenol, xylenol, and tetralin. The present invention also provides a method of forming a sulfonated coal tar distillate salt polymer. The method includes sulfonating the middle fraction to form a middle fraction sulfonic acid mass, optionally adding a first portion of water to the middle fraction sulfonic acid mass to form a mixture, reacting the mixture and an aldehyde to form a condensate, optionally adding a second portion of water to dilute the condensate, and adding a base to form a sulfonated middle fraction salt polymer. Sulfonated middle fraction salt polymers formed in accordance with the method of the invention are useful as dispersants and plasticizers in aqueous cementitious slurries.
