Abstract
Method of forming a composition comprising impregnated polylactic acid (PLA) resin beads, by impregnating PLA resin beads with CO. The method is carried out by contacting the beads with liquid CO, and holding the impregnated beads at a temperature and pressure that prevents the beads from foaming while allowing the level of impregnated COto reduce to about 4 to 20 weight % relative to the total weight of the beads and CO.
