Abstract
The present invention is directed to absorbable polylactone copolymers prepared in part from about 2 to about 80 mole percent glycolide, utilizing a combination of a monofunctional polymerization initiator and a di-functional polymerization initiator, to achieve rates of crystallization of the copolymer of at least about 2 times faster than the rate of crystallization of a copolymer made by a similar process utilizing either the mono-functional or the di-functional polymerization initiator alone. Medical devices containing such copolymers are also disclosed.
