    • The invention relates to a process for preparing an imidized polymer in a mixing or kneading device, by a reaction of a mixture, comprising a polymer, containing anhydride groups or derivatives thereof and an aromatic polyamine compound, wherein the reaction is carried out in the presence of an acid. With this process an imidized polymer can be obtained with a reduced amount of incomplete reacted anhydride groups with respect to the anhydride groups originally present in the polymer as well as a low amount of free and amid-bound aromatic polyamine. The invention further relates to a solid compound, and in particular a solid multifunctional viscosity modifier comprising a polymer comprising between 0.1 and 10 functional groups per 1000 C-atoms, the functional groups comprising aromatic amine based imide groups, wherein the ratio of imide groups with respect to the functional groups is more than 0.85, preferably more than 0.90 and most preferably more than 0.95 and to a lubricating oil, comprising the multifunctional viscosity modifier according to the invention, wherein the amount of low molecular weight aromatic polyamine in the oil is smaller than 10 ppm.

    • The invention relates to a barrier film layer comprising a polymer composition, wherein the polymer composition comprises a. an amount of a highly branched polyesteramide (HBPEA), and b. optionally, an amount of polyvinyl alcohol or a derivative thereof (P(E)VA), wherein the sum of the amount of the HBPEA and the amount of the P (E)VA is at least 30 weight %, calculated relative to the weight of the polymer composition, and wherein the amount of the HBPEA is at least 5 weight %, calculated relative to the weight of the polymer composition, and wherein the polymer composition comprises hydroxyl and/or carboxyl functional groups with a combined hydroxyl and carboxyl value of at least 20 mg KOH/g calculated relative to the polymer composition. The effect of the barrier film according to the invention is that it can be used to enhance the oxygen barrier properties of polymeric substrates, that it does not generate hydrogen chloride gas when incinerated, that it can be used in applications requiring non-invasive control on metal content and that it has improved adhesion on apolar substrates compared to barrier film layers based on a completely hydrolyzed PVA alone. A further advantage of the barrier film layer according to the invention is an improved printability. The invention also relates to a coating composition comprising a polymer composition as described for the barrier film layer. The invention also relates to use of the coating composition for the preparation of a barrier film layer, to a substrate bearing a barrier film layer according to the invention and to an article comprising a substrate according to the invention.
