ABSTRACT:
A granular polyurethane cellular medium for absorbing water-borne, water insoluble hydrocarbons, method for its preparation and production system. The granular medium is formed by prereacting polyisocyanate or a prepolymer with a linear monohydric alcohol to form a prepolymer. This prepolymer subsequently is reacted with a polyol and blowing agent within a flexible sheet bun mold. Following molding of the bun within the flexible sheet, the bun is transferred to a comminution stage within a predetermined time period whereupon it is granulated. The material is fabricable at low cost and under a broad range of environmental conditions permitting flexibility in selecting the site for production of the material. The material exhibits an unusually high affinity for the water-borne contaminant hydrocarbons, does not absorb water and lends itself to low-cost production procedures.
