Patent ID: 7851553

Claim:
A composition comprising at least two incompatible thermoplastic polymers, which are respectively polar and apolar, and a compatibilizing system which consists in at least one polymeric compatibilizer that includes at least two groups of polar and apolar units compatible with said polymers respectively, wherein the composition comprises the product of a hot compounding reaction, in the presence of a crosslinking system, of said compatibilizer in the crosslinkable state with said thermoplastic polymers, wherein in said composition, said compatibilizer is crosslinked and polar and apolar polymer are not crosslinked, wherein said crosslinking system is selected from the group consisting of systems comprising an organic peroxide, systems comprising a phenolic resin, systems comprising a metal oxide and systems comprising a diamine, and wherein the compatibilizer is present in the composition with a mass fraction of between 1% and 25% and the sole crosslinked compatibilizer forms an interphase between the two thermoplastic polar and apolar polymers.
