Patent ID: 8133968

Claim:
A method of preparing a polymer, the method comprising: combining components comprising: at least one hydroxy-containing compound of the formula (Formula I) HO-A-OH; and at least one orthoester of the formula (Formula II) under conditions effective to polymerize at least a portion of the orthoester; and removing byproducts comprising R 14 OH to provide a polymer comprising two or more repeat units of the formula (Formula VI): wherein each R 9 and R 10 independently represents hydrogen or an organic group; each R 11 , R 13 , and R 14 independently represents an organic group; n=0; each A independently represents a group of the formula (Formula III) —Ar 2 —C(R 8 ) 2 —Ar 2 —(B) m —; and wherein each Ar 2 independently represents an arylene group, each R 8 independently represents a methyl group, B represents an aromatic-containing organic group having a linking oxygen attached to the aromatic ring, and m=0 or 1, wherein at least one A represents a structure of the formula:
