The authors concluded that it is possible that ethylene exerts some protection of vinyl acetate units by increasing the steric effects of the polymer backbone through more compact folding, thus leading to more effective shielding of the hydrolyzable units.
Using the methods described by Guo and Karplus, a series of diene models were used to analyze the steric effects that contribute to the torsion potential curve of 9-cis-UAB30.
Because the rate of hydrolysis is limited by steric effects, it decreases with the length of the alkyl substituent on the alkoxide precursor.
