摘要:
The present invention relates to a method for preparing grafted polymers from a polymer made of conjugated diene units and a graft which is a thiol derivative. The method is characterised by the lack of a solvent and of a radical initiator. The grafted polymer can be used advantageously as an additive for a bitumen/polymer composition and enables, in particular, thermoreversible cross-linking.
