04093709 is referenced by 263 patents and cites 4 patents.

The invention concerns orthoester and orthocarbonate polymers having a repeating mer comprising a hydrocarbon radical and a symmetrical dioxycarbon unit of the general formula: ##STR1## WHEREIN R.sub.1 is a multivalent hydrocarbon radical, R.sub.2 and R.sub.3 are hydrocarbon radicals with at least one of R.sub.2 or R.sub.3 bonded to the dioxycarbon through an oxygen linkage, and which polymers are synthesized by reacting a polyol with an orthoester or orthocarbonate. The polymers are useful for making articles of manufacture, including devices and coatings for delivering beneficial agents.
