Abstract

Esta invencion provee varios copolímeros que constan de una primera unidad de repeticion de la formula química (I), en donde R1 y/o R2 son grupos alquilo y una segunda unidad de repeticion que tiene generalmente la formula química (II), y combinaciones de dos o más de las mismas en donde R es un átomo de hidrogeno o un grupo metilo, y la primera unidad de repeticion es menos del 45% en peso del peso total del copolímero. Esta invencion se refiere también al uso de estos copolímeros en la fabricacion de dispositivos quirurgicos absorbibles tales como suturas y recubrimientos para dispositivos médicos. Adicionalmente, se describen mezclas y polioxaésteres que contienen la primera unidad de repeticion.
