Adhesive compositions containing ionene elastomers

A pressure sensitive adhesive composition comprising the ionene elastomer repeating units represented by the formula:

• ##STR32## Wherein:
• R is a lower alkyl group of 1 to 4 carbon atoms;
• R' is a lower alkyl group of 1 to 4 carbon atoms wherein R' may be the same as or different from R, and R' and R may be joined together with or without an additional hetero atom to form a heterocyclic ring;
• X is a halogen selected from the group consisting of Cl, Br, and I;
• X' is a halogen selected from the group consisting of Cl, Br, and I and can be the same as or different from X;
• B is a divalent polymeric moiety having a molecular weight of about 1,000 to about 50,000;
• B' is a divalent polymeric moiety having a molecular weight of about 1,000 to about 50,000 and may be the same as or different from B but, if B and B' are different, at least one of B or B' has a T.sub.g of less than 20.degree. C.;
• AR is a phenylene or substituted phenylene radical;
• Y is a divalent electron-donating sustituent;
• and
• W is a divalent radical selected from the group consisting of (1) a C.sub.2-12 alkylene selected from the group consisting of saturated C.sub.2-12 alkylene, C.sub.2-12 alkylene with one double bond, C.sub.2-12 alkylene with more than one double bond and C.sub.2-12 alkylene with a triple bond, (2) --(CH.sub.2 CH.sub.2 O).sub.2 --CH.sub.2 CH.sub.2 --when Y is oxygen or sulfur and (3) carbonyl, terephthaloyl, or adipoyl when Y is nitrogen and sufficient compatible tackifier to endow the composition with a degree of adhesive tack to provide a pressure sensitive adhesive.
