Recycling of monomers instead of polymer may become an interesting
option against environmental pollution. What conditions should be
applied for such a degradation to be performed.
Poly(lactic acid) (PLA) has received much recent attention because the lactic acid monomer [CH3CH(OH)COOH] from which it is made can be obtained from carbohydrates rather than petroleum. This makes PLA a more “environmentally friendly” polyester. (A further discussion of green polymer synthesis is presented in Chapter 28.) Draw the structure of PLA.
