Abstract:
A polymer comprising at least one mer unit derived by polymerization of the olefinic bond from a halogenated acrylate having the general formula ##STR22##wherein A is oxygen or sulfur, and Z is a group having at most 150 carbon atoms selected from the group consisting of(1) ##STR23##in which each R.sup.1 independently is F, Cl, or Br;(2) ##STR24##which each R.sup.2 independently is(a) a perfluorinated, perchlorinated, or per(chlorofluoro) group (i), (ii), (iii), (iv), or (v) wherein(i) is a C.sub.1 -C.sub.20 aliphatic group,(ii) is a C.sub.3 to C.sub.20 cycloaliphatic alkyl group(iii) is a C.sub.6 -C.sub.20 aryl group,(iv) is a C.sub.7 -C.sub.20 aralkyl group, and(v) is a C.sub.7 -C.sub.20 alkaryl group,(b) F, Cl, Br, I, Q (defined below), R.sup.4 COO--, R.sup.4 O--, --COOR.sup.4, --OSO.sub.2 R.sup.4, or --SO.sub.2 OR.sup.4, wherein R.sup.4 is any group from (a)(i), (a)(ii), (a)(iii), (a)(iv), and (a)(v),or any two adjacent R.sup.2 groups together can form a perfluorinated, perchlorinated, or per(chlorofluoro) cycloaliphatic or aromatic ring moiety in which n fluoro or chloro groups optionally can be replaced by n R.sup.2 groups where n is a whole number in the range of 0 to 25, wherein Q is ##STR25##in which A is as defined as above, with the proviso that all R.sup.2 groups in the molecule can be the same only when R.sup.2 is not Cl, F, Br or I; and each R.sup.3 independently can be(a) a perfluorinated, perchlorinated, or per(chlorofluoro)(i) C.sub.1 -C.sub.20 aliphatic group,(ii) C.sub.3 -C.sub.20 cycloaliphatic group,(iii) C.sub.6 -C.sub.20 aryl group,(iv) C.sub.7 -C.sub.20 aralkyl group, and(v) C.sub.7 -C.sub.20 alkaryl group,(b) F, Cl, Br, I, Q (defined above), R.sup.4 COO--, R.sup.4 O--, --COOR.sup.4, --OSO.sub.2 R.sup.4, or --SO.sub.2 OR.sup.4, wherein R.sup.4 is any group from (a)(i), (a)(ii), (a)(iii), (a)(iv), and (a)(v),or any two adjacent R.sup.3 groups together can form a perfluorinated, perchlorinated, or per(chlorofluoro)cycloaliphatic or aromatic ring moiety in which n fluoro or chloro groups optionally can be replaced by n R.sup.3 groups where n is a whole number in the range of 0 to 25, and R.sup.3 is as defined above;(3)--C(R.sub.f).sub.2 Ewherein both R.sub.f groups together form a perfluorinated, perchlorinated, or per(chlorofluoro) cycloaliphatic ring group or independently comprise perfluorinated, perchlorinated, or per(chlorofluoro)(a) C.sub.1 -C.sub.20 aliphatic groups,(b) C.sub.3 -C.sub.20 cycloaliphatic groups,(c) C.sub.6 -C.sub.20 aryl groups,(d) C.sub.7 -C.sub.20 aralkyl groups, or(e) C.sub.7 -C.sub.20 alkaryl groups,(f) C.sub.4 -C.sub.20 heteroaryl groups,(g) C.sub.4 -C.sub.20 heteroaralkyl groups,(h) C.sub.4 -C.sub.20 heteroalkaryl groups,wherein heteroatoms can be one or more of O, N, and S atoms, with the proviso that at least one R.sub.f group includes one or more of (i) at least one straight-chain C.sub.4 -C.sub.20 aliphatic or C.sub.4 -C.sub.20 cycloaliphatic group, (ii) at least one ether oxygen atom, and (iii) at least one branched C.sub.3 -C.sub.20 aliphatic group, andE is R.sub.f, ##STR26##wherein R.sup.1, R.sup.2, and R.sub.f, and Q are defined as above, and(4)--CR.sub.f (E).sub.2,wherein each E independently is as defined above, and R.sub.f is as defined above; which has been crosslinked by polyfunctional halogenated acrylates.
