全氟弹性体组合物
摘要：
本发明涉及一种全氟弹性体组合物，该全氟弹性体组合物包含：‑至少一种包含碘和/或溴原子的全氟弹性体[全氟弹性体(A)]；‑每100重量份的所述全氟弹性体(A)，从0.5重量份至5重量份的至少一种具有通式(I)的双‑烯烃[双‑烯烃(OF)]；其中R1、R2、R3、R4、R5以及R6，彼此相同或不同，是H、卤素或C1‑C5任选地卤代的基团，有可能包括一个或多个氧基团；Z是直链或支链的C1‑C18任选地卤代的亚烷基或亚环烷基，任选地包含氧原子，或(全)氟聚氧亚烷基；‑每100重量份的所述全氟弹性体(A)，从0.1重量份至3重量份的至少一种有机过氧化物；‑每100重量份的所述全氟弹性体(A)，从0.1重量份至3重量份的至少一种选自下组的有机碱[碱(B)]，该组由以下各项组成：(i)符合通式(B1m)或(B1d)的非芳香族伯胺或酰胺：Rbm‑[C(O)]t‑NH2(B1m)H2N‑[C(O)]t’‑Rdm‑[C(O)]t”‑NH2(B1d)其中：‑t、t’和t”的每一个彼此相同或不同并且在每次出现时是零或1；‑Rbm是具有12至30个碳原子的一价烃非芳香族基团；‑Rdm是具有6至30个碳原子的二价烃非芳香族基团；以及(ii)符合通式(II)(B2m)或(B2d)的脂环族仲胺或叔胺：其中：‑Cy表示二价脂肪族基团，该二价脂肪族基团包含至少4个碳原子，任选地包含一个或多于一个烯键式不饱和双键，并且任选地包含一个或多个链状氮原子，与连接到其上的氮原子形成环；‑Cy’表示三价脂肪族基团，该三价脂肪族基团包含至少5个碳原子，任选地包含一个或多于一个烯键式不饱和双键，并且任选地包含一个或多个链状氮原子，与连接到其上的氮原子形成环。
摘要（英）：

The invention pertains to a perfluoroelastomer composition comprising: at least one perfluoroelastomer comprising iodine and/or bromine atoms [perfluoroelastomer (A)]; from 0.5 to 5 weight parts, per 100 parts by weight of said perfluoroelastomer (A), of at least one bis-olefin [bis-olefin (OF)] having general formula (1) wherein R1, R2, R3, R4, R5 and R6, equal or different from each other, are H, a halogen, or a C1-C5 optionally halogenated group, possibly comprising one or more oxygen group; Z is a linear or branched C1-C18 optionally halogenated alkylene or cycloalkylene radical, optionally containing oxygen atoms, or a (per)fluoropolyoxyalkylene radical; from 0.1 to 3 weight parts, per 100 parts by weight of said perfluoroelastomer (A), of at least one organic peroxide; from 0.1 to 3 weight parts, per 100 parts by weight of said perfluoroelastomer (A), of at least one organic base [base (B)] selected from the group consisting of: (i) non-aromatic primary amines or amides complying with general formula (B1m) or (Bid): Rbm-[C(O)]t-NH2 (B1m) H2N-[C(O)]t'-Rdm-[C(O)]t''-NH2 (Bid) wherein: each of t, t' and t'', equal to or different from each other and at each occurrence is zero or 1; Rbm is a monovalent hydrocarbon non-aromatic group having 12 to 30 carbon atoms; Rdm is a divalent hydrocarbon non-aromatic group having 6 to 30 carbon atoms; and (ii) cycloaliphatic secondary or tertiary amines complying with general formula (II) (B2m) or (B2d) wherein: Cy represents a divalent aliphatic group comprising at least 4 carbon atoms, optionally comprising one or more than one ethylenically unsaturated double bond, and optionally comprising one or more catenary nitrogen atoms, forming a cycle with the nitrogen atom which is connected thereto; Cy' represent a trivalent aliphatic group comprising at least 5 carbon atoms, optionally comprising one or more than one ethylenically unsaturated double bond, and optionally comprising one or more catenary nitrogen atoms, forming a cycle with the nitrogen atom which is connected thereto.
