A detergent composition which is suitable for making into bars for personal washing comprises: (a) 10 to 60% wt. of a synthetic, non-soap detergent; (b) 20 to 60% wt. of water soluble material which is neither soap nor a non-soap detergent and which has a melt...
|6174928||Process for producing fluorinated oligomer having COOH groups at both ends|
A fluorinated oligomer having COOH groups at both end and a .rho.50° value of 1,000 to 10,000 is produced by swelling a fluorine rubber crosslinking product in an organic solvent, followed by decomposition in the presence of a base and a perox...
|5432259||Process for the preparation of fluorinated monomers|
The pyrolysis of fluorine polymers leads to a high yield of pure fluorinated monomers if the finely divided polymer is introduced, with steam, into a fluidized bed reactor which contains an inert, granular material as the fluidized material, the steam fun...
