Biopolymers

Biopolymers

1. polymers

   • are macromolecules that result from joining monomers
   • main characteristics
   • natural polymers
     • are produced by nature
   • synthetic polymers
     • polymerization by addition
     • polymerization by condensation

2. are polymers from a renewable sources

3. three important groups

   • polymers based on renewable sources (starch,cellulose)
   • biodegradable polymers made of monomers biobased (vegetable oils and lactid acid)
   • biopolymers synthesized by microorganisms (PHA)
