Abstract
Polyester compositions are the reaction product of a reaction mixture including at least two different diacids, and at least two different diols. At least one diacid or diol has at least one pendant ethylenically unsaturated group, and at least one diacid or diol has at least one pendant ionic group. The polyester composition has a glass transition temperature in a range of −60° C. to 12° C., and is a vibration-damping, pressure sensitive adhesive.
Claims19
An adhesive article comprising:
- a first carrier layer with a first major surface and a second major surface;
- and
- a first polyester-based ionomeric adhesive layer with a first major surface and a second major surface, wherein the first major surface of the first polyester-based ionomeric adhesive layer is in contact with the second major surface of the first carrier layer, and
- wherein the polyester-based adhesive layer comprises:
- a polyester composition comprising the reaction product of a reaction mixture comprising:
- at least two different diacids;
- at least two different diols;
- wherein at least one diacid or diol has at least one pendant ethylenically unsaturated group, and
- wherein at least one diacid or diol has at least one pendant ionic group;
- wherein the polyester composition has a glass transition temperature in a range of 60° C. to 12° C., and
- wherein the polyester composition is a vibration-damping, pressure sensitive adhesive, and further comprising a film substrate with a first major surface and a second major surface, wherein the second major surface of the first polyester-based ionomeric adhesive layer is in contact with the first major surface of the film substrate.
