摘要 |
There are described block copolyacetals obtainable by cationically initiated polyaddition of (A) polyacetals containing acetaldehyde acetal units and having at least 2 OH groups in the molecule and (B) polyacetals containing acetaldehyde acetal units and having at least 2 vinyl ether groups in the molecule. in a molar ratio of (A):(B) of from 2:1 to 1:2, processes for preparing the block copolyacetals by cationically initiated polyaddition of (A) and (B), and the use of the block polyacetals as additament to reduced-phosphate and phosphate-free detergents and cleaners and as low-foam surfactants in dishwashing compositions.
