Abstract
A composition containing a particulate, absorbent solid and particles of a rapid-dissolving, high molecular weight polymer in admixture is used to soak up and hold hydrocarbons and other organic liquids. The polymer dissolves in the liquid being absorbed and tends to seal the liquid within the absorbent particles and to bind the particles together thus facilitating clean-up.
