Process for the oligomerization of hexafluoropropylene oxide (HFPO) in which the sum of the dimers, trimers, tetramers, pentamers and hexamers represents less than 20% of the weight of the polymerized HFPO, the oligomers other than the dimers, trimers, tetramers, pentamers and hexamers (the remaining oligomers) having an average molecular weight ranging between 1100 and 4000 g/mol, characterized in that the process comprises the steps of contacting hexafluoropropylene oxide (HFPO) at a temperature between &#x2212;30&#xb0; C. to +50&#xb0; C. with a catalyst system selected from potassium fluoride and di-, tri- or tetraethyleneglycol-dimethylether in the presence of a solvent which is selected from perfluorinated aliphatic or aromatic hydrocarbon with more than 3 and less than 12 C-atoms and optionally a polar group but not comprising chlorine or bromine partially fluorinated aliphatic or aromatic hydrocarbon with more than 3 and less than 12 C-atoms and optionally a polar group but not comprising chlorine or bromine at a pressure of less than 3 bars by controlled monomer addition continuous feeding or by adding the monomer in one or two portions (shots).

Polymerisation of hexafluoropropylene oxide

Substituted aminopolyorganosiloxanes (S) containing substituted amino groups which are bonded to silicon atoms of the polysiloxane skeleton via alkylene bridges or mono- or oligo-(alkyleneamino)alkylene bridges, in which the amino groups occurring in the aminopolyorganosiloxanes are substituted at least in part with a radical of the formulaT&#x2014;CH&#x2014;CHOH&#x2014;CH&#x2014;&#x2003;&#x2003;(&#x3b5;),

Modified polyorganosiloxanes, aqueous emulsions thereof, their production and their use

The present invention relates to silicone waxes having plural tertiary or quaternary amino groups, their preparation and their use as softeners in the textile industry. These waxes can be processed into stable aqueous dispersions and lead to products having a pleasant, soft hand.
