Abstract:
A diene rubber comprising 40 to 99.99% by weight of combined units of a conjugated diene monomer, 0 to 50% by weight of combined units of an aromatic vinyl monomer, and 0.01 to 20% by weight of combined units of other vinyl monomer comprising at least one of tertiary amino-containing vinyl monomer and halogen-containing vinyl monomer and wherein at least part of said combined other vinyl monomer is quaternized to form quaternized tertiary amino-containing vinyl monomer units, with the provisos that when said other vinyl monomer comprises combined tertiary amino-containing vinyl monomer units it is quaternized with a monohalogenated hydrocarbon and when said other vinyl monomer comprises combined halogen-containing vinyl monomer units it is quaternized with a tertiary amine, and having a Mooney viscosity ML.sub.1+4, 100.degree. C.) of 10 to 200,wherein the tertiary amino-containing vinyl monomer is a compound of the formulaCH.sub.2.dbd.CR.sup.11 --A.sub.2 --NR.sup.12 R.sup.13where R.sup.11 is a hydrogen atom or a lower alkyl group, R.sup.12 and R.sup.13 are each, independently, an alkyl group, an aryl group or an aralkyl group,A.sub.2 is an alkylene group, an arylene group, an arylene-alkylene group, an alkylene-arylene group, or a linking group of the general formula --C(.dbd.O)--M--R.sup.14 --, in which M is an oxy group or an NH group, and R.sup.14 is an alkylene group, an arylene group, an arylene-alkylene group or an alkylene-arylene group, andR.sup.12 or R.sup.13 may be combined with A.sub.2 to form a heterocyclic ring,and wherein the combined units of the quaternized tertiary amino-containing vinyl monomer have the formula ##STR1##where R.sup.1 is a hydrogen atom or a lower alkyl group, R.sup.2, R.sup.3 and R.sup.4, are each, independently, an alkyl group, an aryl group or an aralkyl group,A.sub.1 is an alkylene group, an arylene group, an arylene-alkylene group, an alkylene-arylene group, or a linking group of the general formula --C(.dbd.O)--M--R.sup.5 --, in which M is an oxy group or an NH group, and R.sup.5 is an alkylene group, an arylene group, an arylene-alkylene group or an alkylene-arylene group, andR.sup.2 or R.sup.3 may be combined with A.sub.1 to form a heterocyclic ring, and X.sub.1 is a halogen atom.
