text: In May 1990, the GFP reached an agreement with the Société chimique de France, becoming its Division of "Polymeric materials and elastomers". In 2001 this agreement was modified to create a "Polymer and Materials Chemistry" Division that was common to the two societies. In 2002, a similar agreement with the Société française de physique created a common "Polymer" Division between the two organizations. The GFP is a founding member of the Fédération française des matériaux (French Materials Federation),  and a member of the European Polymer Federation, whose first conference was organized by the GFP in Lyon in 1986. In 2020, the GFP signed a Memorandum of Understanding with the  Society of Polymer Science Japan.
