Abstract
The present invention relates to a process for the preparation of graft thermoplastic polymers in which at least one thermoplastic polymer (A) is grafted with a functional monomer in the presence of a substance which inhibits or reduces the crosslinking or the depolymerization of (A). This substance may be a stable nitroxide radical. Graft polymers are useful as compatibilizing agents in mixtures of polymers and as coextrusion binders. The invention also relates to multilayer structures including these binders.
