Abstract:
1. A polymer comprising at least 10 mol % of repeating units having a structure selected from the group consisting of Formula (I) and Formula (Ia) for which the variables are defined as follows: Ar is a phenylene ring optionally substituted with from one to four substituents independently selected from the group consisting of halogen, halomethyl, halomethoxy, methyl, methoxy, thiomethyl, nitro, sulfoxide and sulfonyl; R X 1 , X 2 and X 3 are independently selected from the group consisting of O, S and NR 3 ; R R AA has a pendant COOR AA and X defines an X wherein said polymer has a glass transition temperature or crystalline melting temperature greater than 37° C. when fully hydrated in phosphate buffered saline (PBS) (0.1 M, pH 7.4) at 37° C. and said Formula (I) and (Ia) variables are selected so that monomers comprising said Formula (I) and Formula (Ia) repeating units have a solubility in said PBS solution at 37° C. of at least about 3 mg/mL.
