Title: Binder for absorbing hydrocarbon(s) etc. from gases, pastes, etc. - consists of particles of plastic foam, made using only mixt. of oxygen and nitrogen as blowing agent
IPC: C08J9/12
Filed: 1989-09-22
Abstract: A process is claimed for the prodn. of a binder (I) in the form of foamed plastic particles, e.g. polystyrene (PS), for removing esp. hydrocarbons from gases, pastes and slurries; the novelty is that the plastic is foamed using only a mixt. of oxygen and nitrogen as blowing agent. Specifically nitrogen oxygen ratio is 80:20, and the plastic is rigid foam based on PS, S/AN copolymer, ring-sulphonated PS, sec. aluminium-bearing PS, or PS treated with a carboxylic acid, amine, alcohol or ester. (I) is more absorbent than prior-art binders, which may absorb 50 times their own wt. of material, and absorption is faster; specially-treated plastics can be used if required, e.g. as described in DE-OS 2903056. USE/ADVANTAGE - (I) is useful, esp. for absorbing oil spills on water or seashores, etc.. The process enables the prodn.  of highly-absorbent (I) without a hard outer skin (contrast prior0art PS prior-art PS foam particles, which have to be crushed to expose the absorbent foam); the blowing agent is also environmentally harmless, and the low-cost process can be carried out at the point of application, using air as blowing agent.
