Abstract
The present invention relates to a composition based on a heterogeneous PVDF and on an aromatic bis-imide that can be crosslinked by ionizing radiation, in which the heterogeneous PVDF is a copolymer of vinylidene fluoride (VDF) and a comonomer, the said heterogeneous PVDF comprising: one or more discrete domains of VDF-comonomer copolymer; one or more discrete domains of PVDF homopolymer containing at least 50% of the VDF of the heterogeneous PVDF; where the proportion of comonomer is between 1 and 20% by weight of the heterogeneous PVDF. Advantageously, the comonomer of the VDF in the heterogeneous PVDF is hexafluoropropylene (HFP).
Claims9
A composition comprising a heterogeneous polyvinylidene fluoride (PVDF) and an aromatic bis-imide, wherein said composition can be crosslinked by ionizing radiation, wherein said heterogeneous PVDF is a copolymer of vinylidene fluoride (VDF) and a comonomer, and wherein said heterogeneous PVDF comprises:
- a) one or more discrete domains of VDF-comonomer copolymer;
- b) one or more discrete domains of PVDF homopolymer containing at least 50% of the VDF of the heterogeneous PVDF;
- wherein the proportion of comonomer is between 1 and 20 percent by weight of the heterogeneous PVDF homopolymer.
