Abstract
In one embodiment, a selectively-releasable adhesive includes a copolymer formed from a multifunctional alcohol, a multifunctional carboxylic acid, and a glycosaminoglycan (GAG). In one embodiment, an adhesive article includes a backing material having a surface and a layer of adhesive provided on the surface, the adhesive layer having an outer surface opposite to a surface that contacts the backing material, the outer surface being at least partly composed of a copolymer formed from a multifunctional alcohol, a multifunctional carboxylic acid, and a glycosaminoglycan (GAG).
Claims31
A selectively-releasable adhesive comprising:
- a copolymer formed from:
- a multifunctional alcohol,
- a multifunctional carboxylic acid, and
- a glycosaminoglycan (GAG).
A method for making an adhesive article, the method comprising:
- coating a substrate with a release agent;
- applying an adhesive solution to the coated substrate;
- curing the adhesive solution in place on the coated substrate to form a cured adhesive layer;
- applying a backing material to the cured adhesive layer;
- and
- removing the backing material along with the cured adhesive layer from the substrate to obtain an adhesive article.
A method for making an adhesive article, the method comprising:
- synthesizing a poly(diglyceryl decanedioate) (PDD) prepolymer solution;
- coating a substrate with a glycosaminoglycan (GAG) solution;
- applying the poly(diglyceryl decanedioate) (PDD) prepolymer solution to the coated substrate;
- curing the poly(diglyceryl decanedioate) (PDD) prepolymer solution in place on the coated substrate to form an adhesive layer that comprises poly(diglyceryl decanedioate)-co-hyaluronan (PDDH);
- applying a backing material to the adhesive layer;
- rinsing the backing material, adhesive layer, and substrate to dissolve at least some of the GAG solution;
- and
- removing the backing material along with the adhesive layer from the substrate to obtain an adhesive article.
An adhesive article comprising:
- a backing material having a surface;
- a layer of adhesive provided on the surface of the backing material, the adhesive layer having an outer surface opposite to a surface that contacts the backing material, the outer surface being at least partly composed of a copolymer formed from a multifunctional alcohol, a multifunctional carboxylic acid, and a glycosaminoglycan (GAG).
