An amorphous polylactic acid polymer having a weight average molecular weight in the range of about 35，000 to 180，000 is described. The polylactic acid polymer composition can be hammer milled without cryogenics result in the form of particles wherein 90% of the particles have particle size of about 250 μm or less and the material has a glass transition temperature of between about 55° C. to about 58° C. and a relative viscosity of about 1.45 to about 1.95 centipoise.
