Adhesives comprising reaction product of halogenated poly(isobutylene) copolymers and polyamines

An adhesive composition comprising a copolymer of isobutylene repeat units and second repeat units selected from alkene repeat units, para-methyl styrene repeat units, or a combination thereof wherein at least a portion of the second repeat units are directly bonded to one another with a cyclic aliphatic polyamine crosslinker having a melting point greater than 25° C.;

• wherein the cyclic aliphatic polyamine is of the general formula R5—(NR1R2)x wherein R1 and R2 are independently H or alkyl, R5 is a polyvalent alkylene, x is at least two, and R1 and R2 taken together form a cyclic amine.

An adhesive composition comprising the reaction product of at least one halogenated

• copolymer of isobutylene wherein halogen atoms of the copolymer are replaced by a polyamine having a melting point greater than 25° C., thereby crosslinking the copolymer, wherein the halogenated copolymer is of the formula
• wherein a is at least 20, the sum of b, and c is at least one, and X2 is bromine and the polyamine is an aliphatic straight-chain or branched polyamine comprising an alkylene group having at least 6 carbon atoms.
