ABSTRACT:
The biodegradable polymer comprises polymerized lactic acid units of the structure: ##STR1## where n is an integer between 450 and 10,000 and the alpha carbon is a mixture of L- and D-configurations with a preponderance of either D- or L-units, wherein the polymer is suitable for replacement of polystyrene; the biodegradable composition also comprises blends of a physical mixture of polymerized lactic acid units of the formula I, where n is an integer between 450 and 10,000 and the alpha carbon is a mixture of L- and D-configurations with a preponderance of either D- or L-units, and a homopolymer of poly(D-lactic acid) or poly(L-lactic acid), and plasticizers that provide unique properties when intimately dispersed.
