Claims17
A sterile surgical article fabricated from a synthetic absorbable copolymer formed by copolymerizing glycolide as the predominant monomer with a cyclic ester monomer other than glycolide, the improvement comprising employing sequential addition of the monomers in the polymerization wherein said glycolide monomer, said cyclic ester monomer, or a combination of said monomers is substantially completely polymerized before the addition of the other monomer or said combination.
A sterile surgical article fabricated from a synthetic absorbable copolymer comprising a proportion of sequential units having the formula:
- ##STR3## and a proportion of sequential units having the formula:
- ##STR4## wherein formula (II) consists of up to about 50% by weight.
