    摘要: One aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant nucleophilic groups and a crosslinker comprising at least two pendant electrophilic groups. Another aspect of the invention relates to a hydrogel comprising a non-natural polymer comprising a plurality of pendant electrophilic groups and a crosslinker comprising at least two pendant nucleophilic groups. Yet another aspect of the invention relates to a method for reducing lung volume in a patient comprising the step of administering a hydrogel composition as described herein. Further, hydrogels of the invention may be used to achieve pleurodesis, seal brochopleural fistulas, seal an air leak in a lung, achieve hemostasis, tissue sealing (e.g., blood vessels, internal organs), or any combination thereof. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema.

    摘要: A reaction product is prepared by reacting a first polymer having pendant or terminal carboxyl or anhydride groups with a second polymer (e.g. elastomer) having an amine containing terminal group. The second polymer is anionically polymerized. The second polymer is functionalized by reacting the growing anionic chain end with an imine. Then a protic terminating agent terminates the growing chain end. The first and second polymers are reacted by mixing (desirably above their softening temperatures) and forming a blend with improved physical properties over a blend of similar polymers lacking a reactive amine group.
