Unfortunately, it is not possible to export a list of publications from ResearchGate, but it is possible to export bibliographic data in three different formats for each publication individually. See my replies to https://www.researchgate.net/post/Can_I_easily_export_my_publications_from_ResearchGate_into_citations and https://www.researchgate.net/post/Saving_the_publication_list for details and for some historical explanations.
