Comb polymers and their use as dispersants

The invention relates to a comb polymer having repeating units of at least one of the structures of formulae (I) to (IV) wherein R1 represents a polyoxyalkylene group and A represents an organic group, and wherein the comb polymer has end groups of general formula (V) wherein R2 and R3 are independe...

Beschreibung
Zusammenfassung:	The invention relates to a comb polymer having repeating units of at least one of the structures of formulae (I) to (IV) wherein R1 represents a polyoxyalkylene group and A represents an organic group, and wherein the comb polymer has end groups of general formula (V) wherein R2 and R3 are independently selected from a) organic groups having 1 to 24 carbon atoms and b) R1. 本发明涉及一种梳形聚合物，其具有式(I)至(IV)的结构的至少一种的重复单元，其中R1代表聚氧化烯基团且A代表有机基团，并且其中所述梳形聚合物具有通式(V)的端基，其中R2和R3互相独立地选自a)具有1至24个碳原子的有机基团和b)R1。
