Shalaby W Shalaby, Dennis D Jamiolkowski: Isomorphic copolyoxalates and sutures thereof. Ethicon, Wayne R Eberhardt, February 27, 1979: US04141087 (213 worldwide citation)

Synthetic absorbable sutures are prepared from copolyoxalate polymers having isomorphic sequences. The polymers are derived from mixtures of cyclic and linear diols, each having the same carbon chain length of 6 or 8 atoms. The cyclic diol may be aliphatic or aromatic. The diols are polymerized with ...
