  • Use of polyamino acid salts in water-borne adhesive applications
    Patent number: 6174988
    Abstract: This invention relates to an adhesive composition which comprises (a) an adhesive carrier, and (b) an adhesively effective amount of a polyamino acid salt selected from the group consisting of polyaspartic acid salts, polyglutamic acid salts, and copolymers of polyaspartic acid salts with polyglutamic acid salts, and mixtures thereof. The present invention also pertains to an article to which the adhesive composition has been applied, a method for adhering a first substrate to a second substrate employing the polyamino acid salts, and to an improved method for making polyamino acid salts.
