Potential application of PPDO

PPDO polymer is mainly applied for absorbable suture and utilized for the raw material of novel absorbable medical devices. PPDO filament is used as monofilament because the filament obtained from PPDO is tough and flexible. Applicable examples of the medical device obtained from PPDO polymers are shown with color in follows:
