Polystyrene was sulfonated with sulfur trioxide–triethyl phosphate complexes in dichloroethane, the object being to prepare polystyrene sulfonates substantially free of sulfone links between polymer chains. Variations in the sulfone content with reaction conditions were conveniently followed by exclusion ...

The 100 000g supernatant from cod contained mainly high-molecular-weight selenium compounds. Storage of cod or herring in the cold for one week did not significantly affect the proportion of low-molecular-weight selenocompounds. The results indicated that the distribution of low- and high-molecular...
