Poly(lactide) Controlled Polymerization….Shopping List
At bottom is an Aldrich shopping cart.
Lactide: http://www.sigmaaldrich.com/catalog/product/aldrich/367044?lang=en&region=US
(Order 25 367044-25G for $61.20) This is the monomer.
TBD Catalyst: http://www.sigmaaldrich.com/catalog/product/aldrich/345571?lang=en&region=US
(Order 1 of the 5 g size: 345571-5G $57.80). Bifunctional catalyst: hydrogen bonding aid and acyl
transfer.
Anhydrous dichloromethane:
http://www.sigmaaldrich.com/catalog/product/sial/270997?lang=en&region=US
(Order 3 of the 100-mL sizes… 270997-100ML 3 x $39.40 = $118.20) Just the solvent
Anhydrous alcohol:
http://www.sigmaaldrich.com/catalog/product/sial/459836?lang=en&region=US
(Order the 500-mL size: 459836-500ML $77.30) This acts as initiator…must be pure and anhydrous.
Hexane:
http://www.sigmaaldrich.com/catalog/product/sial/296090?lang=en&region=US
(Order the 1-L size 296090-1L for $86.30) Nonsolvent for isolation….low-quality grade OK.
Acetic Acid: Acts as quencher. Assume some is present.
Other things we may need: approximately 10-mL vials, plastic syringes with needles to draw solvent out
of Sure-Seal bottles. Pipetman-style digital pipettors could help, if we don’t have those already; we can
get by with syringes and needles, but preferably the polypropylene kind not the super-cheap medical
ones. Here’s the right kind of syringe:
