PLA = Polylactide = lactic acid monomers chain
PLA degradation � chemical hydrolysis – FIRST STEP
H2O
First step: water attacks the chemical bonds in the amorphous phase and it reduces the polymer chains into
small fragments� molecular weight drops down
+ + +++
+
B.Fontana 12
PLA degradation � chemical hydrolysis – SECOND STEP
Second step: enzymes / microorganisms metabolize these fragments� polymer mass is lowering
The decomposition by-products are incorporated into the cellular physiological processes and they’re finally
excreted asCO2 and H2O
B.Fontana 13
PLA polymer processing
• rheological: lower melt elasticity if compared to polyolefins
• mechanical: a blend of those of PET and PS
• hydrolytically biodegradable
Density [g/cc] 1,24
Tg [°C] 60-65
Tm [°C] 160-170
Drying -- 50 ppm moisture
Temperature control in the stretching phase
Shrinkage control (fixing)
Reduction of:
• molecular weight
• melt viscosity
• crystallization rate

Biolene : applications in the medical market
• implant absorption
• radiotransparency
• no toxicity
• gradual strain transfer to healingtissue
• reduction of rejection of the foreignbody
• material metabolizedinside the human body
• it can be sterilized
• suitable for gradual drug release
