METHOD OF PRODUCING ADHERED SUBSTRATES
First Claim
1. A method of producing adhered substrates comprising:
- providing an adhesive composition in the form of a liquid dispersion, the liquid dispersion comprising solid particles of a first component comprising a co-polymer or a terpolymer prepared from monomers including at least ethylene and vinyl acetate and solid particles of a second component comprising a copolymer prepared from monomers including at least propylene and maleic anhydride dispersed in a third component comprising a non-reactive hydrocarbon that is a liquid at room temperature;
heating and mixing the liquid dispersion at a temperature above about 300°
F. to form a molten blend;
disposing the molten blend between the substrates to be adhered to each other; and
retaining the molten blend between the substrates to be adhered to each other for a set time during which the molten blend cools to form a solid adhesive that adheres the substrates to each other.

Abstract
A method of producing adhered substrates that includes: providing an adhesive composition that is a liquid dispersion when stored at temperatures from about room temperature up to about 140° F., becomes a molten solution when heated to a temperature above about 300° F. and mixed, and then becomes a non-exuding thermoplastic solid adhesive upon cooling below a temperature of about 140° F.; heating and mixing the liquid dispersion at a temperature above about 300° F. to form the molten blend; disposing the molten blend between the substrates to be adhered to each other; and retaining the molten blend between the substrates to be adhered to each other for a set time during which the molten blend cools to form the solid adhesive that adheres the substrates to each other.
