| abstract |
The present invention relates to a hyperbranched polyether of formula (I) R m Q n -0-R 1 (I), where- in Q is a branching unit of formula, n is 2 k -1, m is 2 k , k is 2, 3, 4, 5 or 6, each R is independently a hydrocarbon radical having at least 10 carbon atoms, R 1 is a polymer having a number average molecular weight M n of at least 250 g/mol, wherein each branching unit Q is connected via ether linkage to adjacent branching units Q and each terminal oxygen of Q, not connected to adjacent branching units Q, is connected to R via ether linkage, as well as mixtures thereof. The present invention further relates to formulations comprising said hyperbranched polyether or mixture of ethers as well as their use. |
