The present invention relates to a urea group containing product comprising one or more species of formula (I) R
1
—X—(C═O)—[NH—R
2
—NH—(C═O)—NH—R
3
—NH—(C═O)]
n
—NH—R
2
—NH—(C═O)—X—R
1
(I), 5 wherein R
1
is independently selected from organic groups having (4) to (200) carbon atoms, X is O or NR
4
, wherein R
4
is a hydrogen atom or an aliphatic or aromatic group having (1) to (30) carbon atoms, R
2
is independently selected from hydrocarbyl groups having (4) to (40) carbon atoms, R
3
is independently selected from hydrocarbyl groups having (2) to (40) carbon atoms, and wherein on average (76) to (100) mol % of all R
3
groups contained in the one or more species of formula (I) are hydrocarbyl groups having (2) or (3) carbon atoms, and n is an integer of (2) to (150). The invention further relates to a method of manufacturing such urea group containing products, liquid compositions containing the same and the use of such liquid compositions as rheology control additives. Furthermore, the invention relates to a process for rheology adjustment adding such liquid composition to semi-finished or final products. The invention also relates to an article coated with the liquid composition.
