Abstract:
A process for the preparation of sulfonated polyurethane-urea polymers, which are useful film to film laminating adhesives for flexible packaging in which the urethane-urea polymer component has no amide linkages. The water-based sulfonated polyurethane prepolymers are processed at reduced temperatures and are substantially free of volatile and/or leachable contaminants.
