Abstract
The present invention relates to a urea group containing product comprising one or more species of formula (I) R—X—(C═O)—[NH—R—NH—(C═O)—NH—R—NH—(C═O)]—NH—R—NH—(C═O)—X—R(I), 5 wherein Ris independently selected from organic groups having (4) to (200) carbon atoms, X is O or NR, wherein Ris a hydrogen atom or an aliphatic or aromatic group having (1) to (30) carbon atoms, Ris independently selected from hydrocarbyl groups having (4) to (40) carbon atoms, Ris independently selected from hydrocarbyl groups having (2) to (40) carbon atoms, and wherein on average (76) to (100) mol % of all Rgroups 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.
