Abstract:
Silicone-polyether block copolymers prepared by organomodification of branched polysiloxanes having terminal and/or lateral SiH functions or linear polysiloxanes having lateral and/or terminal SiH functions by means of polyethers or polyether mixtures, characterized in that the polyethers used have a polydispersity Mw/Mn in the range from 1.0 to 1.5 and/or ratios Mn/MWIN and Mw/MWIN in the range from 0.7 to 1.3, their preparation and use and also polymer articles produced therewith.
