Abstract
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.
