1. A degradable molded article comprising:

  • a) a nontoxic hydrolytically degradable polymer, comprising repeating monomer or comonomer units selected from the group consisting of;

    ##STR6## wherein X is the same or different and is O or NR'"'"' with R'"'"' being the same or different and being H, hydrocarbyl, or substituted hydrocarbyl;

    R1, R2, R3 and R4 can be the same or different and are hydrogen, hydrocarbyl containing 1 to 24 carbon atoms, or substituted hydrocarbyl containing 1 to 24 carbon atoms, and where n1 and n2 can be the same or different and are an integer of from 1-12;

    b) a nontoxic modifier, wherein said modifier is compatible with said polymer and said modifier is nonvolatile and nonfugitive;

    c) wherein said molded article has a tensile strength of less than about 20,000 psi; and

    d) wherein said polymer has a weight average molecular weight from about 100,000 to about 500,000.
