| titleOfInvention | Fluoroelastomer composition |
| abstract | The present invention relates to a fluoroelastomer composition comprising: (a) vinylidene fluoride based fluoroelastomers [ fluoroelastomers (A)]Comprising recurring units derived from vinylidene fluoride (VDF) and recurring units derived from at least one additional (per) fluorinated monomer; the fluoroelastomer (a): -has a polydispersity index (I) between 1.5 and 3.5 MWD ) Comprising an amount of at least 3mmol/kg and at most 6mmol/kg of a compound having the formula-CF 2 CH 2 Polar end groups of OH, and-further comprises an amount satisfying the following inequality having the formula-CF 2 H、‑CF 2 CH 3 And optionally-OC (O) -R H (wherein R is H Is C 1 ‑C 6 Alkyl) chain end group: [ -CF 2 CH 2 OH]+[‑CF 2 H]+[‑CF 2 CH 3 ]+[‑OC(O)R H ]≤30+(2x10 6 )/M n (ii) a (b) At least one polyhydroxylated curing agent; (c) at least one accelerator; (d) at least one metal oxide selected from the group consisting of divalent metal oxides; and (e) optionally, at least one metal hydroxide, wherein the amount of said metal hydroxide, if present, is less than 3phr, based on 100 parts by weight of fluoroelastomer (a). |
