polymer solution was placed on a Teflon film-casting dish and the solvent was allowed to

evaporate. 1H NMR (300 MHz, CDC13, ppm): 6 1.15-1.20 (m, 4H), 1.20-1.42 (m, 22H),

Synthesis of Valinol Polymer (9)

 A schlenk flask was placed under vacuum for 24 hours at 50 C containing 1.00

gram of the L-valinol diene monomer (3) and a small stir bar. After 24 hours 9.0 mg (1.1

x 10-2 mmol) of 2nd generation Grubbs' catalyst was added to the schlenk flask. The

mixture was stirred under vacuum at 50 C for five days. After polymerization was

determined to be complete, a small volume of THF was added to dissolve the polymer

(9). The resultant polymer solution was placed on a Teflon film-casting dish and the

solvent was allowed to evaporate. H NMR (300 MHz, CDC13, ppm): 6 0.90-0.97 (m,

Synthesis of Leucinol Polymer (10)

 A schlenk flask was placed under vacuum for 24 hours at 50 C containing 0.50

grams L-leucinol diene monomer (4) and a small stir bar. After 24 hours 7.3 mg (8.6 x

10-3mmol) of 2nd generation Grubbs' catalyst was added to the schlenk flask. The
