Summary:Stable aqueous poly(urea/urethane) polymers and dispersions are made that do not require the inclusion of chain extenders, curing agents or crosslinking agents. The disclosed poly(urea/urethane) dispersions can be used to make articles such as films and gloves with reduced chance of chemical and biological allergic reaction to skin, and which exhibit improved puncture and tear resistance when compared to such articles made with other materials.
