Polymerisation of vinylidene cyanide, acrylonitrile, diamines and ureas.

Sulfolane can be used as a polymerisation solvent in a number of systems, such as water soluble polysaccharide polymers prepared from glucose solution in Sulfolane with a phosphoric acid catalyst.
• Vinylidene cyanide, vinyl esters and acrylonitrile.
• Diamines and ureas.
• Co-polymerisation of aromatic polycarboxylic acids with polyisocyanates, polycarboxylic acids with partially acylated diamines and/or aminocarboxylic acids, aromatic diamines with a tricarboxylic acid or anhydride and trimellitic anhydride with 4,4' - diphenylmethane diisocyanate.
• Polyether polyols have been prepared from 1,3,5-triazines and oxirane compounds.
• Linear aromatic polyethers have been produced by the condensation of 4,' - dihydroxybiphenyl, or hydroquinone with 4,4' - dichlorodiphenyl sulphone.
• Polysiloxanes from halosilanes.
• Separation and recovery of polysulphone resins.
