| 摘要 |
There is disclosed certain hyperbranched polyester amides with a cloud point of at least 50° C. in water with end groups selected from: two or more i] tertiary amine functional end groups ii) ammonium functional end groups, iii) polyalkylene glycol functional end groups; iv) quaternary ammonium zwitterionic end groups and/or v) other ionic groups (such as phosphate or sulfate), that are useful in various end uses such as a flocculant. |
