Abstract
A significant disadvantage of the use of polylactic acid (PLA) has been overcome by the use of styrene maleic anhydride copolymer in combination with an epoxy functional styrene-acrylate oligomeric chain extender. The composition also often exceeds a threshold of 65° C. in heat deflection temperature.
