A polyesteramide suitable for use in the fabrication of absorbable surgical devices such as monofilament and multifilament sutures, films, sheets, plates, clips, staples, pins, screws, and the like, is obtained by reacting a monoalkanolamine such as ethanolamine with a diacid halide such as succinic acidchloride to provide a diamidediol and thereafter reacting the diamidediol with the same or different diacid halide under polymerization conditions to form the polyesteramide.
L'invention concerne un polyesteramide utile pour la fabrication de dispositifs chirurgicaux résorbables, tels que des fils de suture à un ou plusieurs brins, des films, des feuilles, des plaques, des pinces, des agrafes, des broches, des vis et analogues. Le polyesteramide est obtenu par mise en réaction d'une monoalcanolamine, telle que l'éthanolamine, avec un halogénure de diacide, tel que du chlorure d'acide succinique, afin d'obtenir un diamidediol, lequel est mis à réagir par la suite avec le même halogénure de diacide ou un halogénure différent dans des conditions de polymérisation, en vue de former le polyesteramide.
