Rate coefficients have been measured for the alkalinehydrolysis of 3-substituted phenyl 2-acetyl-and 2-benzoyl-benzoates in 70%(v/v) dioxane–water at several temperatures. The enthalpies and entropies of activation have been evaluated. The effects of substitution have been assessed by means of the Hammett equation. Comparison of the reaction constants with those for model systems, as well as the relative

The present invention encompasses polymer compositions comprising aliphatic polycarbonate chains containing functional groups that increase the polymer's ability to wet or adhere to inorganic materials. In certain embodiments, chain ends of the aliphatic polycarbonates are modified to introduce silicon-containing functional groups, boron-containing functional groups, phosphorous-containing functional groups, sulfonic acid groups or carboxylic acid groups.
