Abstract:
1. A bimodal polymer composition, comprising: (a) a first amount of a fully amorphous bioabsorbable polymer having a first hydrolysis rate and a first molecular weight distribution; and (b) a second amount of said fully amorphous bioabsorbable polymer having a second hydrolysis rate and a second molecular weight distribution having a weight average molecular weight between about 10,000 to about 50,000 Daltons, the weight average molecular weight ratio of said first molecular weight distribution to said second molecular weight distribution is at least about two to one; wherein a substantially homogeneous blend of said first and second amounts of said fully amorphous bioabsorbable polymer is formed in a ratio of between about 50/50 to about 95/5 weight/weight percent, said substantially homogeneous blend having a hydrolysis rate greater than each of said first hydrolysis rate and said second hydrolysis rate.
