LINEAR POLYDIMETHYLSILOXANE-POLYOXYALKYLENE BLOCK COPOLYMERS LINKED VIA SIC GROUPS AND VIA CARBOXYLIC ESTER GROUPS, A PROCESS FOR PREPARING THEM AND THEIR USE

The invention provides linear polydimethylsiloxane-polyoxyalkylene block copolymers containing Si-C groups and carboxylic ester groups and having repeating (A1BA2B) units where A1 and A2 are two different polydimethylsiloxane units of the general formula (I) with a number of Si atoms N=(n+2) of 1516...
