Abstract: The present invention refers to a method for improving the storage stability and/or transport stability of polymer (A) comprising the following steps: a) providing polymer (A) selected from the group consisting of copolymers of ethylene and a C4C12 alpha olefin comonomer, copolymers of propylene and mixtures thereof containing additionally comonomer units comprising hydrolysable silane groups; b) providing a stabilizer (B) selected from the group consisting of sterically hindered phenols, alkyltri-alkoxysilanes, alkenyltrialkoxysilanes and mixtures thereof; c) mixing polymer (A) and stabilizer (B) to obtain a stabilized polymer composition (I); and d) transferring the stabilized polymer composition (I) obtained in step c) in a container comprising at least one barrier layer. In addition, the present invention relates to the use of stabilizer (B) for improving the storage stability and/or transport stability of polymer (A) stored and/or transported in a container having a barrier layer.
