Abstract
The invention relates to a hot melt processable pressure sensitive adhesive comprising at least one elastomer, organophilic clay plate-like particles, and at least one non-volatile organophilic exfoliating agent. Also disclosed are articles prepared therefrom and methods pertaining thereto.
Claims24
A composition comprising:
- at least one elastomer;
- organophilic clay plate-like particles;
- and
- at least one non-volatile organophilic exfoliating agent;
- wherein the composition is a hot melt processable pressure sensitive adhesive.
2 more elements
A composition comprising:
- at least one elastomer;
- organophilic clay plate-like particles;
- and
- at least one non-volatile organophilic exfoliating agent;
- wherein the organophilic clay plate-like particles are oriented and wherein the composition is a hot melt processable pressure sensitive adhesive.
2 more elements
A method comprising the step of:
- combining, in a solventless manner and in any order, components comprising:
- at least one elastomer;
- at least one organophilic clay;
- and
- at least one non-volatile organophilic exfoliating agent;
- and
- shear mixing the components in any order at a sufficient temperature to form a hot melt processable, pressure sensitive adhesive composition comprising organophilic clay plate-like particles.
4 more elements
A solventless method comprising the steps of:
- shear mixing at least one organophilic clay and at least one non-volatile organophilic exfoliating agent at a sufficient temperature in order to form a composition comprising organophilic clay plate-like particles and the non-volatile organophilic exfoliating agent;
- and
- mixing the composition with an elastomer at a sufficient temperature in order to form a hot melt processable, pressure sensitive adhesive composition comprising organophilic clay plate-like particles.
