Heat-reversible polymers with nitroxide functions

摘要

The invention concerns a method for preparing resins branched or crosslinked by heat treatment with a polymer in the presence of a multinitroxide and optionally a free radical initiator, to obtain a resin exhibiting properties of beat reversibility. The initial polymer can be a rubber or a thermoplastic polymer. The resins obtained provide conditions for use similar to those of the initial polymers while exhibiting enhanced mechanical properties.
